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: USP4

Ubiquitin carboxyl-terminal hydrolase 4 (USP4) is a specialized cysteine protease with a predicted molecular weight of 109 kDa. USP4 is a member of the peptidase C19 family and the human protein shares 91% amino acid sequence identity with its mouse ortholog. USP4 is ubiquitinated on multiple sites, and deubiquitination of these sites requires USP4 catalytic activity. USP4 interacts with CtIP protein and the MRN (MRE11-RAD50-NBS1) complex to promote DNA double-strand break repair. Other reported USP4 targets include HDAC2, ADORA2A, PDPK1 and TRIM21. This recombinant protein contains a C-terminal 6-His tag.
