Cytokines ELISA Kits
DeQuanto® INTERFERON GAMMA (IFN-γ) DETECTION ELISA KIT (High Sensitive)
Product Description
The kit is a sandwich enzyme immunoassay for in vitro quantitative measurement of IFNg in human serum, plasma, tissue homogenates, cell lysates, cell culture supernates and other biological fluids.
Test Principle
The microplate provided in this kit has been pre-coated with an antibody specific to IFNg. Standards or samples are then added to the appropriate microplate wells with a biotin-conjugated antibody specific to IFNg. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain IFNg, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of IFNg in the samples is then determined by comparing the O.D. of the samples to the standard curve.
