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: UBE2F

Ubiquitin-conjugating Enzyme E2F (UBE2F) is a NEDD8-conjugating enzyme (E2) (1). It is a 185 amino acid (aa) protein with a predicted molecular weight of 21 kDa. The human protein exhibits approximately 96% aa sequence identity with its mouse and rat orthologs. UBE2F is involved the covalent attachment of NEDD8 to target proteins in a process termed neddylation. For example, UBE2F appears to participate in the neddyylation of Cullin 5 (1). Members of the Cullin family (Cullin 1-7) are scaffold proteins that can incorporate into multimolecular complexes termed Cullin RING Ubiquitin Ligases (CRLs) (2). CRLs make up the largest subset of Ubiquitin Ligases (E3), and their activity is promoted by neddylation of associated Cullin family proteins (3).
