Dengue IgG ELISA

1.Product Overview

The Dengue IgG ELISA Kit is a highly sensitive and specific in - vitro diagnostic tool designed for the qualitative and semi - quantitative detection of Dengue virus - specific immunoglobulin G (IgG) antibodies in human serum or plasma samples. Ideal for both clinical diagnosis and epidemiological research, this kit helps identify past or persistent Dengue infections, complementing IgM - based early - stage detection methods. It is available in a convenient 96 - well microplate format, ensuring efficient high - throughput testing.

2.Detection Principle

2.1 Direct ELISA Principle

Antigen Coating: The wells of the microplate are pre - coated with purified Dengue virus antigens (such as envelope glycoprotein E or non - structural protein NS1).

Sample Incubation: Patient serum or plasma samples are added to the wells. If present, Dengue - specific IgG antibodies in the sample bind to the immobilized viral antigens.

Enzyme - Labeled Conjugate Binding: A horseradish peroxidase (HRP) - labeled anti - human IgG antibody is then added. This conjugate binds to the captured Dengue - specific IgG antibodies, forming an “antigen - IgG - enzyme - labeled antibody” complex.

Color Development and Detection: Addition of the 3,3',5,5' - tetramethylbenzidine (TMB) substrate initiates a color - forming reaction catalyzed by HRP. After stopping the reaction with sulfuric acid (H₂SO₄), the absorbance is measured at 450 nm using a microplate reader. The optical density (OD) value is directly proportional to the concentration of Dengue - specific IgG antibodies in the sample.

5.Performance Characteristics

Clinical Sensitivity: Demonstrated high detection rates in clinical trials, accurately identifying patients with past Dengue infections, especially those with IgG antibody levels above 15 AU/mL.

Clinical Specificity: Minimizes false - positive results, with negligible cross - reactivity against antibodies from other flavivirus infections (e.g., Zika, Japanese encephalitis virus).

Reproducibility: Consistent results across different operators and laboratories, with intra - assay coefficient of variation (CV) ≤8% and inter - assay CV ≤10%.

6. Applications

Clinical Diagnosis: Confirming past Dengue virus infections, especially when IgM results are negative but clinical suspicion remains. Useful for differentiating primary and secondary Dengue infections based on IgG seroconversion patterns.

Epidemiological Surveillance: Assessing the prevalence of Dengue in populations, tracking the spread of the virus over time, and evaluating the effectiveness of vaccination programs.

Research Studies: Investigating the immune response to Dengue virus, studying the kinetics of IgG antibody production, and validating new diagnostic methods.

7. Precautions and Limitations

For In - Vitro Diagnostic Use Only: The assay should be performed by trained laboratory personnel following standard biosecurity protocols.

Sample Handling: Ensure samples are free from hemolysis, lipemia, and contamination, as these may affect test results.

Result Interpretation: Results should be interpreted in conjunction with clinical symptoms, patient history, and other laboratory findings. A positive result does not necessarily indicate current infection.

Limitations: The kit may not detect very low - level IgG antibodies or antibodies from rare Dengue virus strains. False - negative results can occur in the early stages of primary infection when IgG has not yet seroconverted.
