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: CTRP2/C1qTNF2

Complement C1q tumor necrosis factor-related protein 2 (C1qTNF2), also known as CTRP-2 or zacrp2 is an approximately 30 kDa member of the C1q family of secreted proteins (1, 2). Like other members of that family, CTRP2 contains a collagen-like region and one C1q-like domain (3). CTRP2 shares 42% amino acids identity with adiponectin at the presumed functional globular domain (4) and is expressed in stromal vascular cells (5). CTRP2 circulates as a trimeric glycoprotein in plasma (6), and can also form homo-oligomer or hetero-oligomer with other CTRPs (7). C1qTNF2 has been shown to phosphorylate AMPK and ACC in skeletal muscle leading to an increase in glycogen accumulation and fatty acid oxidation (8). C1qTNFs are of clinical interest as diagnostic or therapeutic targets in diseases where energy homeostasis is unbalanced such as obesity, insulin resistance, and type 2 diabetes (2).
