Carrier Free

CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins. Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration. The carrier free version does not contain BSA.

In general, we advise purchasing the recombinant protein with BSA for use in cell or tissue culture, or as an ELISA standard. In contrast, the carrier free protein is recommended for applications, in which the presence of BSA could interfere.

Background: NPRB/NPR2

Human Natriuretic Peptide Receptor-2 (NPR2), also known as NPRB, ANP-RB or guanylyl Cyclase-B, is a member of the guanylyl cyclase family of proteins. NPR2 is a type I transmembrane glycoprotein that contains a 436 amino acid extracellular domain (ECD) (aa 23‑458) for ligand binding, and a 569 amino acid cytoplasmic domain that contains both a protein kinase domain and a carboxyl-terminal guanylate cyclase domain. NPR2 is expressed most highly in in bone, brain, fibroblasts, heart, kidney, liver, lung, uterine, and vascular smooth muscle tissue (1). NPR2 operates as an oligomer and binds both ANP (atrial natriuretic peptide) and BNP (B type natriuretic peptide), and NPR2 is the principal receptor of CNP (C type natriuretic peptide) (1, 2). Ligand binding to the extracellular ligand binding domain, plus ATP to the intracellular kinase domain activates a cytoplasmic guanylate cyclase (2). NPR2 pathway play a critical role in regulation of skeletal growth (3), and patients with single defect NPR2 alleles are statistically shorter than the average population (4). Over the extracellular domain, human NPR2 is 97% and 96% identical to mouse and rat NPR2, respectively.
