Anti-NT-proBNP (39-76) Antibody

Mouse monoclonal antibody from Antibodies.com targets the N-terminal pro-B-type natriuretic peptide (NT-proBNP) within amino acid residues 39–76. NT-proBNP is a 76 amino acid fragment cleaved from the prohormone proBNP and is widely used as a circulating biomarker for cardiac stress, ventricular dysfunction, and congestive heart failure in cardiovascular research.

The unconjugated IgG1 reagent is supplied as 1 mg of purified protein in liquid format, enabling integration into multiple immunoassay workflows. Documented applications include western blot, immunohistochemistry, and flow cytometry for studies of natriuretic peptide processing and ventricular remodeling. Because the antibody binds an internal epitope of the prohormone fragment rather than the mature BNP ring, it provides specific detection relevant to cardiac biomarker investigations.
