C-Type Natriuretic Peptide (CNP) (1–22), human TFA（Cat No.:I044324）is a synthetic peptide corresponding to the biologically active 22-amino acid form of human CNP, a member of the natriuretic peptide family. Unlike ANP and BNP, CNP primarily acts in a paracrine/autocrine manner and binds to natriuretic peptide receptor-B (NPR-B) to regulate vascular tone, inhibit smooth muscle proliferation, and support endochondral bone growth. It plays key roles in cardiovascular, skeletal, and neural systems. The TFA (trifluoroacetate) salt enhances peptide stability and solubility, making it suitable for experimental studies in vascular biology and endocrinology.
