Principe du test
This Rabbit VB12 ELISA Kit is an in vitro competitive enzyme-linked immunosorbent assay for the quantitative measurement of VB12.
A microplate has been precoated with VB12. Samples, standards and Anti-VB12 Antibody (Biotin) are added to the wells, where VB12 in the sample competes with the fixed VB12 to bind to the antibody. The wells are washed to remove unbound material and HRP-conjugated streptavidin is added. After incubation, the wells are washed again and TMB substrate is added. The TMB substrate is catalyzed by HRP to produce blue colouration. The reaction is terminated by addition of Stop Solution which stops the colour development and produces a colour change from blue to yellow. The intensity of the signal is inversely proportional to the amount of VB12 in the sample and the intensity is measured at 45 nm.
