ELISA Test Principle:
The microtiter plate provided in Human CTLA4 ELISA Kit has been pre-coated with an CTLA4 antibody specific to Human Cytotoxic T-lymphocyte protein 4 .Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody preparation specific for Human Cytotoxic T-lymphocyte protein 4 and then avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. Then a TMB substrate solution is added to each well. Only those wells that contain Human Cytotoxic T-lymphocyte protein 4, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm
