Product Description:Human cytokeratin fragment antigen 21- 1 ELISA Kit allows for the in vitro quantitative determination of cytokeratin fragment antigen 21-1 concentrations in serum, plasma, tissue homogenates, cell culture supernates or other biological fluids.

ELISA Test Principle:
The microtiter plate provided in Human cytokeratin fragment antigen 21- 1 ELISA Kit has been pre-coated with an cytokeratin fragment antigen 21-1 antibody specific to cytokeratin fragment antigen 21-1 .Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody preparation specific for cytokeratin fragment antigen 21-1 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 cytokeratin fragment antigen 21-1, 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.The concentration of cytokeratin fragment antigen 21-1 in the samples is then determined by comparing the O.D. of the samples to the standard curve.
