Background: IgG is the most abundant immunoglobulin in serum and is predominately involved in the secondary immune response. The IgG subclasses are designated 1, 2, 3 and 4 based on their relative prevalence in human serum.
Assay Principle: Human IgG will bind to the affinity purified capture antibody coated on the microtiter plate. After appropriate washing steps, horseradish peroxidase labeled polyclonal anti-human IgG antibody binds to the captured protein. Excess antibody is washed away and TMB substrate is used for color development at 450 nm. A standard calibration curve is prepared along with the samples to be measured using dilutions of Human IgG. Color development is proportional to the concentration of IgG in the samples.
Specifications:
- Sensitivity: 0.084 ng/ml
- Specificity: Total Human IgG (Does not distinguish IgG subclasses.)
- Range: 0.2-200 ng/ml
- Sample Type: Serum, plasma, hybridoma cell supernatants, ascites or other biological fluids.
- Cross-Reactivity: Pooled normal plasma from Cynomolgus monkey was assayed and minor cross-reactivity was observed. Pooled normal plasma from mouse, rat and rabbit were assayed and no significant cross-reactivity was observed.
