C-type natriuretic peptide (CNP, pGC-B activator) is the native particulate guanylyl cyclase B receptor (pGC-B) activator.CNP induces anti-remodeling actions in the heart and kidney through the generation of the second messenger cGMP.CNP selectively activates pGC-B and generates cGMP in vitro.CNP is abundantly expressed in the endothelium and kidneys as well as the heart, but to lesser extent than trial natriuretic peptide (ANP) and b-type natriuretic peptide (BNP).CNP is produced as a prohormone that is cleaved intracellularly by the enzyme, furin, to yield a 53-AA intermediate form (C53).

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
