Brain-type Natriuretic Peptide (BNP) is a nonglycosylated peptide that is produced predominantly by ventricular myocytes and belongs to the natriuretic peptide family. Proteolytic cleavage of the 12 kDa BNP precursor gives rise to N-terminal Pro BNP (NT-proBNP) and mature BNP. N-terminal proB-type natriuretic peptide (NT-proBNP); a useful marker of heart failure (HF); is considered to be secreted mainly from the ventricle; increased serum NT-proBNP levels are also encountered in conditions such as atrial fibrillation (AF) and atrial septal defect in patients without HF.
Recombinant Human Brain-type Natriuretic Peptide is produced by our E.coli expression system and the target gene encoding His27-Arg102 is expressed with a 6His; Flag tag at the N-terminus.
