Intended use

Intended use:

BNP is mainly expressed by ventricular myocardium in response to volume overload and increased filling pressure. BNP has a cleavable signal sequence. Mature BNP consists of 108 amino acids (proBNP or BNP- 108), and undergoes cleavage resulting in physiologically active BNP-32 and additional C-terminal fragments (cf. http://www.uniprot.org/uniprot/P16860#PRO_0000001532), along with a physiologically inactive N- terminal peptide comprising amino acids 1-76, which is further degraded proteolytically. BNP has a key role in cardiovascular homeostasis with biological actions including natriuresis, diuresis, vasorelaxation, and inhibition of renin and aldosterone secretion. A high concentration of BNP in the bloodstream is indicative of heart failure.

Intended applications:

  • Cardiac impairment, acute myocardial infarction, (left ventricular dysfunction)
  • Renal failure
  • Obesity and diabetes
  • Various forms of secondary hypertensions
  • Therapy monitoring of heart failure patients
