tcue1634 ELISA Kit for Brain Natriuretic Peptide (BNP)

This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to Brain Natriuretic Peptide (BNP) has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled Brain Natriuretic Peptide (BNP) and unlabeled Brain Natriuretic Peptide (BNP) (Standards or samples) with the pre-coated antibody specific to Brain Natriuretic Peptide (BNP). After incubation the unbound conjugate is washed off. Next, avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. The amount of bound HRP conjugate is reverse proportional to the concentration of Brain Natriuretic Peptide (BNP) in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of Brain Natriuretic Peptide (BNP) in the sample.
