Description
Intended Uses: The kit is a sandwich enzyme immunoassay for the in vitro quantitative measurement of CASP8 in human tissue homogenates, cell lysates, cell culture supernates or other biological fluids.
Principle of the Assay: The microtiter plate provided in this kit has been pre-coated with an antibody specific to CASP8. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody preparation specific to CASP8. 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 CASP8, 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 CASP8 in the samples is then determined by comparing the O.D. of the samples to the standard curve
