Human Immunoglobulin G, Igg Elisa Kit, 96T

The Human Immunoglobulin G (IgG) ELISA Kit is a highly sensitive and specific assay designed for the quantitative detection of IgG levels in human serum, plasma, culture media, and other biological fluids. This kit is ideal for research into immune responses, antibody production, and immunological disorders.

Purpose

• Quantification of IgG Levels:
  • Detect and measure IgG concentrations in human biological samples for research into immunity and disease.
• Sample Compatibility:
  • Suitable for human serum, plasma, and other biological fluids.

Principle

The assay utilizes a Sandwich-ELISA technique to provide accurate and reliable quantification of IgG. Below is the process:

1. Pre-Coated Plate:
   • Microelisa stripplate wells are pre-coated with an antibody specific to IgG.
2. Sample and Standard Addition:
   • Standards and samples are added to the wells, where IgG in the sample binds to the immobilized antibody.
3. HRP-Conjugated Detection:
   • A Horseradish Peroxidase (HRP)-conjugated antibody specific to IgG is added, forming a sandwich complex with the captured IgG.
4. Washing Step:
   • Free and unbound components are washed away to minimize background interference.
5. Substrate Reaction:
   • TMB substrate solution reacts with HRP, producing a blue color in wells containing IgG.
6. Stop Reaction and Measurement:
   • A stop solution is added, changing the color from blue to yellow. Optical density (OD) is measured at 450 nm using a spectrophotometer.
7. Quantification:
   • IgG concentrations are calculated by comparing OD values to a standard curve.

Key Features

1. High Sensitivity and Specificity:
   • Accurately detects low levels of IgG with minimal cross-reactivity or interference.
2. Wide Sample Compatibility:
   • Suitable for serum, plasma, culture media, and other biological fluids.
3. Quantitative Results:
   • Provides precise measurement of IgG concentrations using a standard curve.
4. Ease of Use:
   • Includes pre-coated plates and ready-to-use reagents for a straightforward workflow.
5. Reproducibility:
   • Ensures consistent and reliable results across multiple experiments.
