Recombinant Human Natriuretic Peptides B/NPPB is produced with our E. coli expression system. The target protein is expressed with sequence (His27-His134) of Human NPPB. Human Natriuretic peptides B acts as a cardiac hormone, it is associated with many biological actions, such as diuresis, natriuresis, vasorelaxation, which inhibits the secretion of rennin and aldosterone. It acts as a paracrine antifibrotic factor in the heart. Natriuretic peptides B can help restore the body balance of salt and water, improves the heart function. Natriuretic peptides B binds and stimulates the cGMP production of the NPR1 receptor and binds the clearance receptor NPR3.
