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: IFN-epsilon

Interferon-epsilon (IFN-epsilon ) is a secreted, approximately 18 kDa member of the type I interferon family of molecules (1). Mature mouse IFN-epsilon shares 55% amino acid sequence identity with human and rat IFN-epsilon, respectively. IFN-epsilon signals through IFN-alpha / beta R1 and IFN-alpha / beta R2 and contributes to TNF-alpha induced signaling (2, 3). It is constitutively expressed in epithelial cells lining the lung, intestines, testes, and female reproductive tract, and it is further up-regulated in the uterus by estrogen
(2-6). IFN-epsilon provides mucosal barrier protection against the pathogens Chlamidia and Herpes simplex virus 2 (2). It induces B cell activation and the attraction of CD8+ T cells to sites of virus infection (5, 7).
