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: Otubain-2

Otubain-2 is a C65 type peptidase and a member of the ovarian tumor (OTU) protein super-family found in eukaryotes, viruses and pathogenic bacterium. Otubain-2 associates with the E3 ubiquitin ligases TRAF3 and TRAF6, and has been shown to negatively regulate virus-induced type I IFN induction and the antiviral responses mediated by these ligases. This recombinant protein contains a C-terminal 6-His tag.
