Carrier Free

What does CF mean?

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.

What formulation is right for me?

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: Angiopoietin-like Protein 3/ANGPTL3

Angiopoietin-like 3 (ANGPTL3) is a secreted glycoprotein that is structurally related to the angiopoietins (1-3). Mature mouse ANGPTL3 contains an N-terminal coiled-coil domain and a C‑terminal fibrinogen-like domain (4). ANGPTL3 is expressed in the liver from early in development through adulthood (4, 5). Full length ANGPTL3 circulates in the plasma as do the proteolytically separated N- and C‑terminal fragments containing the coiled‑coil domain and fibrinogen-like domains, respectively (6, 7). ANGPTL3 is found as 70 kDa, 50 kDa, and 32 kDa species and can form weakly associated noncovalent multimers in vitro (5, 6). ANGPTL3 directly inhibits lipoprotein lipase (LPL), an enzyme responsible for hydrolyzing circulating triglycerides (8). This activity requires a putative heparin-binding motif that is N-terminal to the coiled-coil domain (6). Proteolytic removal of the fibrinogen-like domain from the N-terminal fragment serves to activate ANGPTL3 and increase its ability to inhibit LPL in vitro and function in vivo (6). ANGPTL3 promotes an increase in circulating triglyceride levels without altering VLDL or HDL secretion or uptake (6-8). ANGPTL3 knockout mice are hypolipidemic and have elevated LPL activity (9). ANGPTL3 expression in vivo is upregulated by LXR agonists and downregulated by insulin, leptin, and TR beta agonists (10-12). Dysregulated ANGPTL3 expression and elevated plasma triglyceride levels are characteristic of some strains of obese and diabetic mice, (7, 8, 11). ANGPTL3 does not bind Tie-1 or Tie-2 but its fibrinogen-like domain interacts with integrin alpha V beta 3 to induce endothelial cell adhesion, migration, and neovascularization (13). ANGPTL3, secreted by fetal liver cells, also promotes the expansion of hematopoietic stem cells (14). Mature mouse ANGPTL3 shares 22%-30% amino acid (aa) sequence identity with ANGPTL1, 2, 4, 6, and 7. It shares 77% aa sequence identity with human ANGPTL3.
