Human E Selectin ELISA Kit (A560)

Human E Selectin ELISA Kit

Sandwich (quantitative)

This E Selectin enzyme linked immunosorbent assay (ELISA) applies a technique called a quantitative sandwich immunoassay. The microtiter plate has been pre-coated with an Anti-E Selectin Antibody. Standards or samples are then added to the microtire plate wells and E Selectin, if present, will bind to the antibody pre-coated on the wells. In order to quantify the amount of E Selectin present in the sample, Anti-E Selectin Antibody (Biotin) is added to each well to "sandwich" the E Selectin immobilised on the plate. The microtiter plate then undergoes incubation, followed by thorough washing of the wells to remove all unbound components. Next, Avidin-Biotin-Peroxidase Complex is added to each well for a short incubation period, followed by thorough washing of the wells to remove all unbound conjugates. Next, a TMB (3,3',5,5' tetramethyl-benzidine) substrate solution is added to each well. The enzyme (HRP) and substrate are allowed to react over a short incubation period. Only those wells that contain E Selectin will exhibit a change in colour. The enzyme-substrate reaction is terminated by the addition of a stop solution and the colour change is measured spectrophotometrically at a wavelength of 450nm ± 2nm.
