Product Datasheets

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.


Formulation Lyophilized from a 0.2 μm filtered solution in MOPS,NaCl and CHAPS with Trehalose.
Reconstitution Reconstitute at 500 μg/mL in water.
Shipping The product is shipped at ambient temperature. Upon receipt, store it immediately at the temperature recommended below.
Stability & Storage: Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
  • 12 months from date of receipt, -20 to -70 °C as supplied.
  • 1 month, 2 to 8 °C under sterile conditions after reconstitution.
  • 3 months, ≤ -20 °C under sterile conditions after reconstitution.

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). Mouse Betatrophin is 183 amino acids (aa) in length and shares 72% aa identity with human Betatrophin. Betatrophin is a crucial modulator in lipid metabolism. It can form a complex with the N-terminal of ANGPTL3, and the complex is necessary for inhibition of LPL and triglyceride modulation (2). Betatrophin did not control beta-cell expansion in the mouse model (3). In addition to the lipid and glucose metabolism, ANGPTL8 has been reported to be involved in many other disorders (4).
