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: EGF

EGF (Epidermal Growth Factor) is expressed as a transmembrane protein that is proteolytically cleaved to generate soluble forms. It signals through EGF R/ErbB1 which heterodimerizes with ErbB2, ErbB3, or ErbB4 and can also associate with PDGF R beta and HGF R/c-MET. During development, EGF regulates thymocyte differentiation, neuroglia production, and adipocyte maturation. In the adult, EGF plays a role in mammary gland lactogenesis, fibroblast mitosis, dissociation of the extracellular matrix, and cell migration.
