Human platelet-derived growth factor-BB (PDGF-BB) ELISA KitHuman
The kit is for the quantitative level of PDGF-BB in the sample, adopt purified Human PDGF-BB to coat microtiter plate, make solid-phase antibody, then add PDGF-BB to wells, Combine PDGF-BB antibody with labeled HRP to form antibody-antigen -enzyme-antibody complex, after washing completely, add TMB substrate solution, TMB substrate becomes blue color at HRP enzyme-catalyzed, reaction is terminated by the addition of a stop solution and the color change is measured at a wavelength of 450 nm. The concentration of PDGF-BB in the samples is then determined by comparing the O.D. of the samples to the standard curve.
