Human CD40L ELISA Kit

製品の詳細

Human CD40L ELISA Kit ab99991 is a sandwich ELISA to measure Human CD40L in serum, plasma, cell culture supernatant with a sensitivity of 6 pg/ml.

How the assay works

This assay employs an antibody specific for Human CD40L coated on a 96-well plate. Standards and samples are pipetted into the wells and CD40L present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-Human CD40L antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of CD40L bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.
