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: USP1

USP1 (Ubiquitin-Specific-processing Protease 1, also known as Ubiquitin carboxyl-terminal hydrolase 1) is a deubiquitinating enzyme of the C19 peptidase family and functions as a negative regulator of the Fanconi Anemia pathway. Reported substrates of USP1 include monoubiquitinated FANCD2 and monoubiquitinated PCNA. USP1 plays important roles in DNA damage responses and cancer-related processes, and inhibiting the function of this deubiquitinase sensitizes some cancer cells to chemotherapy. By itself, USP1 is nearly completely inactive and requires a protein binding partner, UAF1 (USP1-Associated Factor 1, also known as WD Repeat-containing protein 48 or WDR48) to stimulate its deubiquitinase activity. In addition to the naturally occurring substates listed above, the USP1/UAF1 complex has been demonstrated to cleave K6, K33, and K63-linked polyubiquitin chains.
