NT-ProANP (N-Terminal Pro Atrial Natriuretic Peptide) BioAssay(TM) ELISA Kit (Porcine)

Sample Type:, Serum, plasma, tissue homogenates and other biological fluids. Intended Use: Sandwich ELISA, Double Antibody, Sensitivity: <0.188ng/ml, Range: 0.313-20ng/ml, Specificity: Porcine, Test Principle: This BioAssay(TM) kit was based on sandwich enzyme-linked immune-sorbent assay technology. Anti-NT-ProANP antibody was pre-coated onto 96-well plates. And the biotin conjugated anti-NT-ProANP antibody was used as detection antibodies. The standards, test samples and biotin conjugated detection antibody were added to the wells subsequently, and wash with wash buffer. HRP-Streptavidin was added and unbound conjugates were washed away with wash buffer. TMB substrates were used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the NT-ProANP amount of sample captured in plate. Read the O.D. absorbance at 450nm in a microplate reader, and then the concentration of NT-ProANP can be calculated.
