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: Reg1B

Reg1B also called Lithostatine-1-beta or Pancreatic stone protein 2 (PSP2) is a type I subclass member of the Reg gene family. The Reg multigene family consists of four subclasses, types I, II, III and IV based on the primary structures of the encoded proteins of the genes. Reg1B is also a member of the Reg family of secreted C-type lectin domain-containing pancreatic proteins (1, 2). The human Reg1B cDNA encodes 166 amino acids protein which contains a 22 aa signal peptide and the 144 aa secreted mature protein. Reg1B shares 86% animo acide sequence identity with Reg1A and like Reg1A is secreted by the exocrine pancreas and associated with islet cell regeneration and diabetogenesis. Reg family proteins were also shown to cause Schwann cell proliferation during regeneration of motor neurons (3).
