Formulation, Preparation and Storage

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 8/Betatrophin

Betatrophin (also called ANGPTL8, lipasin and RIPL), a novel secretory protein from liver and fatty tissues, is believed to be involved in lipid and glucose metabolism. It is most homologous to ANGPTL3 but lacks the fibrinogen-like domain of ANGPTL3 and other ANGPTL family members (1). Human Betatrophin is 183 amino acids (aa) in length and shares 72% aa identity with mouse Betatrophin. Betatrophin is expressed in the liver, white adipose, and brown adipose tissues. It is a recently identified hormone which has been associated with two functionally important processes in the development of type 2 diabetes and obesity, insulin resistance as well as being a crucial modulator in lipid metabolism through regulation of serum triglyceride levels (2, 3). Betatrophin can form a complex with the N-terminal of ANGPTL3, and this complex is necessary for inhibition of lipoprotein lipase (LPL) activity and triglyceride modulation (4). Elevated levels of circulating betatrophin in the blood may be associated with gestational diabetes mellitus (GDM) and polycystic ovary syndrome (PCOS) (5, 6). Increased levels of Betatrophin in plasma and adipose tissue may also be associated with hypertension, coronary artery disease (CAD), and peripheral artery disease (PAD) (7, 8). The role of Betatrophin in inducing pancreatic beta-cell proliferation is controversial, as it did not control beta-cell expansion in the mouse model (9, 10). In addition to the lipid and glucose metabolism, ANGPTL8 has been reported to be involved in many other disorders such as non-alcoholic fatty liver disease and renal dysfunction (11).
