Umano RANK Kit Elisa (A698)

Human RANK ELISA Kit

Sandwich (quantitative)

This RANK enzyme linked immunosorbent assay (ELISA) applies a technique called a quantitative sandwich immunoassay. The microtiter plate has been pre-coated with an Anti-RANK Antibody. Standards or samples are then added to the microtire plate wells and RANK, if present, will bind to the antibody pre-coated on the wells. In order to quantify the amount of RANK present in the sample, Anti-RANK Antibody (Biotin) is added to each well to "sandwich" the RANK 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 RANK 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.
