Human Soluble Cluster of differentiation 40 ligand,sCD40L ELISA Kit
Purpose
This kit allows for the determination of sCD40L concentrations in Human serum, blood plasma, and other biological fluids.
Principle of the assay
The kit assay Human sCD40L level in the sample，use Purified Human sCD40L antibody to coat microtiter plate wells, make solid-phase antibody, then add sCD40L to wells, Combined sCD40L antibody which With HRP labeled，become antibody-antigen- enzyme-antibody complex, after washing Completely, Add TMB substrate solution, TMB substrate becomes blue color At HRP enzyme-catalyzed, 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 sCD40L in the samples is then determined by comparing the O.D. of the samples to the standard curve.
