Equine CD40L (Cluster Of Differentiation 40 Ligand) ELISA kit

This kit applies sandwich ELISA method for the quantitative detection of CD40L (Cluster Of Differentiation 40 Ligand) in equine samples. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Horse CD40L. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Horse CD40L. 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 Horse CD40L, 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 Horse CD40L in the samples is then determined by comparing the OD of the samples to the standard curve.
