Anti-Pro-BNP Antibody, Biotinylated

Brain natriuretic peptide (BNP) is a polypeptide of 134-amino acids comprised of a 26-amino acid signal peptide (Met1-Ser26), a 76-amino acid N-terminal fragment (NT-proBNP) (His27-Arg102), and a 32-amino acid mature polypeptide of brain natriuretic peptide 32 (BNP-32)(Ser103-His134). BNP-32 is secreted by the ventricles of the heart in response to excessive stretching of heart muscle cells (cardiomyocytes). BNP-32 is co-secreted along with NT-proBNP which is biologically inactive. Both BNP-32 and NT-proBNP markers are used for screening, diagnosis of acute congestive heart failure (CHF). The plasma concentrations of both BNP and NTproBNP are also typically increased in patients with asymptomatic/symptomatic left ventricular dysfunction.

The antibody is stable for at least 1 year from the date of receipt when stored at -20°C to -70°C. Reconstituted antibody can also be aliquotted and stored at 4°C for 1 month or at -20°C to -70°C in a manual defrost freezer for many months without detectable loss activity. Please avoid freeze-thaw cycles.

The Mouse anti-human proBNP antibody specifically detects target derived from human recombinant protein at various concentrations. Cross reactivity with mouse and rat are expected from sequence similarity.
