产品描述
This assay employs the competitive enzyme immunoassay technique. Determine the level of Rat BNP(Brain Natriuretic Peptide) in the sample. Add standard or sample to the microplate that have been pre-coated with Rat BNP(Brain Natriuretic Peptide) antigen. Add Biotin-conjugated anti-Rat BNP(Brain Natriuretic Peptide) antibody. It is then combined with HRP-conjugated streptavidin to form an immune complex, then incubated and washed to remove unbound enzyme, and then added to the chromogenic substrate TMB to produce a blue color, and converted to the final yellow under the action of acid. Finally, the absorbance (OD) value was measured at 450 nm. The concentration of Rat BNP(Brain Natriuretic Peptide) in the sample is inversely proportional to the OD value. The concentration of Rat BNP(Brain Natriuretic Peptide) in the sample can be calculated by drawing a standard curve.
