Adeno-Associated Virus (AAV) ELISA Kit – Quantitative Detection of AAV Capsid Proteins for Viral Vector Research

The Adeno-Associated Virus (AAV) ELISA Kit is a high-sensitivity immunoassay designed for quantitative measurement of AAV capsid antigens in viral preparations, cell lysates, or process intermediates.
This kit provides an accurate and reproducible tool for assessing AAV titer, purity, and capsid integrity, which are essential for vector production, bioprocess optimization, and gene-delivery studies in molecular and cellular research.

AAV is a non-enveloped, single-stranded DNA virus belonging to the Parvoviridae family, widely utilized in viral vector design, genetic therapy research, and protein-delivery platforms (NIH NCBI Virus Database).
Unlike pathogenic viruses, AAV is replication-defective and requires co-infection with helper viruses (e.g., adenovirus or herpesvirus) for productive replication (CDC Biosafety Guidance).

Molecular Biology of AAV

AAV genomes are approximately 4.7 kb in length and consist of two open reading frames:

  • rep, encoding replication and regulatory proteins (Rep78, Rep68, Rep52, Rep40)

  • cap, encoding structural capsid proteins VP1, VP2, and VP3, which form the icosahedral viral shell (NCBI Gene Database).

The AAV capsid plays a critical role in:

  • Host-cell binding via heparan sulfate proteoglycan or sialic acid receptors

  • Endosomal trafficking

  • Nuclear entry and uncoating

  • Encapsulation of recombinant genomes for gene-transfer studies (NIH Molecular Biology of the Cell).

Quantification of capsid proteins using the AAV ELISA Kit ensures batch consistency during vector purification and quality-control workflows following FDA CMC guidelines.

AffiELISA® Adeno-Associated Virus (AAV) ELISA Kit

Principle of the AAV ELISA Kit

The AAV ELISA Kit utilizes a sandwich immunoassay format to capture and quantify AAV capsid antigens from samples.

Assay workflow:

  1. Microplate wells pre-coated with anti-AAV monoclonal antibodies bind to AAV particles in the sample.

  2. Unbound material is removed by washing.

  3. Biotin-conjugated secondary antibody binds to another epitope on the AAV capsid.

  4. Streptavidin-HRP conjugate amplifies the signal.

  5. Color development using TMB substrate is read at 450 nm.

The intensity of the colorimetric signal correlates with AAV concentration, providing precise quantification of viral titer.
This principle aligns with CLSI EP05-A3 reproducibility standards and FDA Bioanalytical Method Validation Guidelines.

8-Hydroxy-2′-deoxyguanosine (8-OHdG) ELISA Kit – Quantitative Detection of Oxidative DNA Damage Markers

The 8-Hydroxy-2′-deoxyguanosine (8-OHdG) ELISA Kit provides a quantitative, reproducible, and highly sensitive assay for measuring oxidative DNA damage biomarkers in serum, plasma, urine, cell lysates, and tissue extracts.
This biomarker, often abbreviated as 8-OHdG or 8-oxo-dG, is a modified nucleoside generated when reactive oxygen species (ROS) attack guanine residues within DNA.
Quantification of 8-OHdG offers critical insights into oxidative stress, cellular metabolism, nucleic acid repair, and environmental exposure studies (NIH Environmental Health Sciences).

Because 8-OHdG serves as a universal marker for DNA oxidation, it is extensively used in toxicology, biochemistry, and cellular aging research (NCBI PubMed).

Scientific Background of 8-Hydroxy-2′-deoxyguanosine

Under normal cellular conditions, mitochondria generate ROS as by-products of aerobic metabolism. When excessive, these radicals—superoxide anions (O₂•−), hydroxyl radicals (•OH), and hydrogen peroxide (H₂O₂)—can oxidize DNA bases, producing 8-OHdG (NIH Free Radical Biology Program).

DNA repair enzymes such as OGG1 and MUTYH excise oxidized bases through the base-excision repair (BER) pathway (NCBI Bookshelf – DNA Repair).
Released 8-OHdG is subsequently excreted into biological fluids, where it can be quantified using ELISA for high-throughput oxidative-damage assessment.

Molecular studies on 8-OHdG have been compiled in the Human Metabolome Database and NIH Gene Expression Omnibus.

AffiELISA® Mouse 8-hydroxy-2-deoxyguanosine | 8-OHdG | ELISA Kit

Principle of the 8-OHdG ELISA Kit

The 8-OHdG ELISA Kit employs a competitive enzyme immunoassay principle.
Microplate wells are pre-coated with 8-OHdG conjugate. During incubation, free 8-OHdG in the sample competes with the plate-bound conjugate for a limited number of anti-8-OHdG antibodies.
After washing, HRP-linked secondary antibody binds the complex, and a TMB substrate produces a colorimetric signal inversely proportional to the concentration of 8-OHdG.

Assay detection wavelength: 450 nm
Quantification range: typically 0.1 – 200 ng/mL
Sensitivity: ~0.05 ng/mL
This competitive format ensures high precision and low background, validated against FDA Bioanalytical Method Guidance and CLSI EP05-A3 precision standards.

HRP-conjugated secondary antibody Signal generation 2–8 °C
TMB substrate Color development Room temperature
Stop solution Reaction termination RT
Sample diluent / wash buffer Matrix balance 2–8 °C

Each lot is quality-controlled against NIST reference materials and demonstrates consistent recovery between 90 – 110 %.

Sample Preparation and Handling

AffiELISA® Chicken Haptoglobin, Hpt/HP ELISA Kit

Structural and Molecular Features of Haptoglobin

Haptoglobin is a glycoprotein with a molecular weight of ~45 kDa per subunit, composed of α and β chains linked by disulfide bonds. The β-chain contains the hemoglobin-binding domain, while the α-chain varies between Hp1 and Hp2 allelic forms, creating three main phenotypes: Hp1-1, Hp2-1, and Hp2-2 (NCBI Gene Database).

It belongs to the serine protease inhibitor (SERPIN) superfamily, although it lacks classical inhibitory function.
The HP gene resides on chromosome 16q22.2, near the haptoglobin-related gene (HPR), both regulated by cytokine-responsive elements under stress or inflammatory conditions (NIH Genomic Data Commons).

Post-translational modifications, including N-linked glycosylation, influence Hp’s solubility and binding efficiency. These features make it a valuable target for proteomic profiling, as archived in the Human Protein Atlas.

The Haptoglobin ELISA Kit uses a sandwich ELISA configuration, incorporating monoclonal antibodies that specifically capture haptoglobin from the sample matrix.
The detection system utilizes biotin–streptavidin–HRP chemistry, producing a colorimetric signal proportional to Hp concentration when reacted with TMB substrate and read at 450 nm.

Assay Workflow:

  1. Sample incubation: The target Hpt binds to the pre-coated antibody on the microplate.

  2. Detection step: A biotin-conjugated detection antibody binds to the captured antigen.

  3. Enzyme conjugation: Streptavidin-HRP binds biotin.

  4. Substrate reaction: Addition of TMB yields a blue color.

  5. Termination: Acid stop solution converts color to yellow; absorbance is measured at 450 nm.

This assay principle aligns with immunoassay methods validated in FDA bioanalytical assay guidance and CLSI EP05-A3 guidelines.

Biological Role and Research Relevance

 Hemoglobin Binding and Oxidative Regulation

Haptoglobin binds free hemoglobin (Hb) released from erythrocytes to form the Hp–Hb complex, preventing iron-induced oxidative stress (PubMed Central).
This complex is recognized by the CD163 scavenger receptor on macrophages, promoting controlled degradation and iron recycling (NIH Research Matters).

 Acute Phase Response

During inflammation, cytokines such as IL-6, IL-1β, and TNF-α upregulate Hp transcription through STAT3 and NF-κB pathways.
This mechanism is well-documented in U.S. National Library of Medicine resources.

 Molecular Pathway Interactions

Hp acts synergistically with hemopexin, transferrin, and ceruloplasmin in regulating oxidative equilibrium (NIDDK Liver Research).
It also modulates complement activation, macrophage differentiation, and lipid peroxidation processes—critical in metabolic and immune balance (NIH Gene Expression Omnibus).

Data Analysis and Curve Fitting

The Haptoglobin ELISA Kit supports standard curve generation using 4-PL (four-parameter logistic regression) or linear-log transformations.
Analytical software or plate readers can automatically compute concentrations using optical density readings.

Advanced Applications in Research

 Proteomics and Biomarker Discovery

Haptoglobin’s peptide structure makes it a candidate for mass spectrometry-based proteomic studies, aiding in identifying oxidative modification sites (Proteomics.gov).

 Molecular Immunology

Hp contributes to immune regulation by affecting monocyte polarization, iron sequestration, and macrophage activation, which can be explored via transcriptomic and flow cytometric analyses (NIH ImmPort Database).

 Environmental and Stress Biology

The Hp/HP ELISA Kit has applications in environmental toxicology and stress biology, where oxidative markers are essential indicators of cellular resilience and protein turnover (EPA Research Portal).

The macrophage activator GcMAF-RF, in accordance with its traits, corresponds to comparable preparations that are made accessible to the market by overseas firms, and may be thought-about as a brand new biologically lively preparation with a large spectrum of motion. Of biggest curiosity is its skill – via the activation of macrophages – to boost the adaptive immunity. In this regard, two areas of therapeutic use of the GcMAF-RF are proposed. The preparation shall be in demand in the subject of most cancers therapy, and, in addition, it may be used in the therapy of quite a few neurodegenerative pathologies. The early signs of nasopharyngeal carcinoma (NPC) are usually not apparent, and it’s troublesome to make early analysis. A case-control research was carried out to determine potential biomarkers and established a analysis mannequin for nasopharyngeal carcinoma.

Neoadjuvant vascular-targeted photodynamic therapy improves survival and reduces recurrence and progression in a mouse model of urothelial cancer

Neoadjuvant vascular-targeted photodynamic therapy improves survival and reduces recurrence and progression in a mouse model of urothelial cancer

Locally superior urothelial cancer has excessive recurrence and progression charges following surgical remedy. This highlights the necessity to develop neoadjuvant methods which are each efficient and well-tolerated. We hypothesized that neoadjuvant sub-ablative vascular-targeted photodynamic therapy (sbVTP), by way of its immunotherapeutic mechanism, would enhance survival and scale back recurrence and progression in a murine model of urothelial cancer. After urothelial tumor implantation and 17 days earlier than surgical resection, mice acquired neoadjuvant sbVTP (WST11; Tookad Soluble, Steba Biotech, France). Local and systemic response and survival served as measures of therapeutic efficacy, whereas immunohistochemistry and move cytometry elucidated the immunotherapeutic mechanism. Data evaluation included two-sided Kaplan-Meier, Mann-Whitney, and Fischer actual checks.

Tumor quantity was considerably smaller in sbVTP-treated animals than in controls (135 mm3 vs. 1222 mm3, P < 0.0001) on the day of surgical procedure. Systemic progression was considerably decrease in sbVTP-treated animals (l7% vs. 30%, P < 0.01). Both median progression-free survival and general survival have been considerably larger amongst animals that acquired sbVTP and surgical procedure than amongst animals that acquired surgical procedure alone (P < 0.05). Neoadjuvant-treated animals additionally demonstrated considerably decrease native recurrence. Neoadjuvant sbVTP was related to elevated early antigen-presenting cells, and subsequent enhancements in long-term reminiscence and will increase in effector and energetic T-cells in the spleen, lungs, and blood.

In abstract, neoadjuvant sbVTP delayed native and systemic progression, extended progression-free and general survival, and decreased native recurrence, thereby demonstrating therapeutic efficacy by way of an immune-mediated response. These findings strongly assist its analysis in scientific trials. The Taiwan Smell Identification Test (TWSIT) was developed and efficiently administered in Taiwanese inhabitants since 2015. However, for sanitation cause, the unique liquid-jar type of this take a look at will not be applicable. The commercialized TWSIT was then re-designed as “scratch-and-sniff” model: the TIBSIT (Top International Biotech, Taipei, Taiwan).

Hundreds of RT-qPCR kits can be found in the marketplace for SARS-CoV-2 prognosis, some of them with emergency use authorization (EUA) by the Food Drug Administration (FDA) or their nation of origin company, but additionally many of them with none impartial scientific efficiency analysis. We carried out a scientific analysis for 2 Chinese SARS-CoV-2 RT-PCR kits out there in South America, COVID-19 Nucleic Acid Test Kit (eDiagnosis Biomedicine, Wuhan, China) and 2019-nCoV Nucleic Acid Diagnostic Kit (Sansure Biotech, Changsha, China), for RT-qPCR SARS-CoV-2 prognosis utilizing the FDA EUA 2019-nCoV CDC package (IDT, Coralville, IA) as gold normal.

We discovered a superb scientific efficiency and analytical sensitivity for each kits with sensitivity values of 100% and 95.3% and estimated restrict of detection of 500 copies/mL and 1,000 copies/mL, for eDiagnosis and Sansure Biotech kits, respectively. COVID-19 Nucleic Acid Test Kit (eDiagnosis) and 2019-nCoV Nucleic Acid Diagnostic Kit (Sansure Biotech) are each made in China and maintain EUA by the Chinese CDC. Also, Sansure Biotech package has EUA by the FDA. In conclusion, our outcomes endorse the use of these two commercially out there kits imported to Ecuador for SARS-CoV-2 prognosis, as that they had the same scientific efficiency because the gold normal from the CDC.

Leveraging Marine Natural Products as a Platform to Tackle Bacterial Resistance and Persistence

Leveraging Marine Natural Products as a Platform to Tackle Bacterial Resistance and Persistence

ConspectusAntimicrobial resistance to present antibiotics represents one of many best threats to human well being and is rising at an alarming price. To additional complicate therapy of bacterial infections, many power infections are the results of bacterial biofilms which are tolerant to therapy with antibiotics due to the presence of metabolically dormant persister cell populations. Together these threats are creating an rising burden on the healthcare system, and a “preantibiotic” age is on the horizon if vital motion will not be taken by the scientific and medical communities. While the golden period of antibiotic discovery (1940s-1960s) produced a lot of the antibiotic courses in scientific use at this time, adopted by a number of many years of restricted growth, there was a resurgence in antibiotic drug discovery lately fueled by the tutorial and biotech sectors.

Historically, nice success has been achieved by growing next-generation variants of present courses of antibiotics, however there stays a dire want for the identification of novel scaffolds and/or antimicrobial targets to drive future efforts to overcome resistance and tolerance. In this regard, there was no extra priceless supply for the identification of antibiotics than pure merchandise, with 69-77% of accepted antibiotics both being such compounds or being derived from them.Our group has developed a program centered on the chemical synthesis and chemical microbiology of marine pure merchandise with uncommon buildings and promising ranges of exercise towards multidrug-resistant (MDR) bacterial pathogens.

As we’re motivated by making ready and finding out the organic results of those molecules, we aren’t initially pursuing a organic query however as an alternative are permitting the noticed phenotypes and actions to information the last word challenge path. In this Account, our latest efforts on the synoxazolidinone, lipoxazolidinone, and batzelladine pure merchandise might be mentioned and positioned within the context of the sphere’s best challenges and alternatives. Specifically, the synoxazolidinone household of 4-oxazolidinone-containing pure merchandise has led to the event of a number of chemical strategies to put together antimicrobial scaffolds and has revealed compounds with potent exercise as adjuvants to deal with bacterial biofilms. Bearing the identical 4-oxazolidinone core, the lipoxazolidinones have confirmed to be potent single-agent antibiotics.

Finally, our artificial efforts towards the batzelladines revealed analogues with exercise towards a variety of MDR pathogens, highlighted by non-natural stereochemical isomers with superior exercise and simplified artificial entry. Taken collectively, these research present a number of distinct platforms for the event of novel therapeutics that may add to our arsenal of scaffolds for preclinical growth and can present perception into the biochemical processes and pathways that may be focused by small molecules within the battle towards antimicrobial-resistant and -tolerant infections. We hope that this work will serve as inspiration for elevated efforts by the scientific neighborhood to leverage artificial chemistry and chemical microbiology towards novel antibiotics that may fight the rising disaster of MDR and tolerant bacterial infections.

capital raised, outcomes from mergers and acquisitions, patents granted to MIT mental property licensees, drug candidates found and US drug approvals-a key benchmark of innovation within the biopharmaceutical trade. As of December 2017, Orange Book listings for 4 accepted small-molecule medicine cite MIT patents, however one other 31 FDA-approved medicine (excluding candidates acquired after section 3) had some involvement of MIT licensees. Fifty-five % of the latter had been both a new molecular entity or a new organic entity, and 55% had been granted precedence evaluate, a sign that they handle an unmet medical want.

Recent Advances within the Evaluation of Serological Assays for the Diagnosis of SARS-CoV-2 Infection and COVID-19

Few information on the diagnostic efficiency of serological exams for extreme acute respiratory syndrome coronavirus 2 (SARS-CoV-2) an infection are presently out there. We evaluated sensitivity and specificity of 5 completely different extensively used industrial serological assays for the detection of SARS-CoV-2-specific IgG, IgM, and IgA antibodies utilizing reverse transcriptase-PCR assay in nasopharyngeal swab as reference customary take a look at. The methodology described right here could also be a helpful framework for different educational establishments to monitor outcomes of mental property within the therapeutics area

A complete of 337 plasma samples collected within the interval April-June 2020 from SARS-CoV-2 RT-PCR optimistic (n = 207) and destructive (n = 130) topics had been investigated by one point-of-care lateral stream immunochromatographic assay (LFIA IgG and IgM, Technogenetics) and 4 totally automated assays: two chemiluminescence immunoassays (CLIA-iFlash IgG and IgM, Shenzhen YHLO Biotech and CLIA-LIAISON XL IgG, DiaSorin), one electrochemiluminescence immunoassay (ECLIA-Elecsys® whole predominant IgG, Roche), and one enzyme-linked immunosorbent assay (ELISA IgA, Euroimmune.

The general sensitivity of all IgG serological assays was >80% and the specificity was >97%. The sensitivity of IgG assays was decrease inside 2 weeks from the onset of signs starting from 70.8 to 80%. The LFIA and CLIA-iFlash IgM confirmed an general low sensitivity of 47.6 and 54.6%, whereas the specificity was 98.5 and 96.2%, respectively. The ELISA IgA yielded a sensitivity of 84.3% and specificity of 81.7%. However, the ELISA IgA consequence was indeterminate in 11.7% of circumstances.
