Human VEGFR2 ELISA Kit (A739)

Human VEGFR2 ELISA Kit

Sandwich (quantitative)

This VEGFR2 enzyme linked immunosorbent assay (ELISA) applies a technique called a quantitative sandwich immunoassay. The microtiter plate has been pre-coated with an Anti-VEGFR2 Antibody. Standards or samples are then added to the microtire plate wells and VEGFR2, if present, will bind to the antibody pre-coated on the wells. In order to quantify the amount of VEGFR2 present in the sample, Anti-VEGFR2 Antibody (HRP) is added to each well to "sandwich" the VEGFR2 immobilised on the plate. The microtiter plate then undergoes incubation, followed by thorough washing of the wells to remove all unbound components. 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 VEGFR2 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.
