二.Human ProBNP ELISA Kit簡介：

The RayBiotech Human proBNP (pro-Brain Natriuretic Peptide) ELISA (Enzyme-Linked Immunosorbent Assay) kit is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of human proBNP in serum (human proBNP concentration is pretty low in normal serum/plasma, it may not be detected in this assay), plasma, cell culture supernatants and urine. This assay employs an antibody specific for human proBNP coated on a 96-well plate. Standards and samples are pipetted into the wells and proBNP present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-human proBNP antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of proBNP bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.
