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: Fc gamma RIIIA/CD16a

Receptors for the Fc region of IgG (Fc gamma Rs) are members of the Ig superfamily that function in the activation or inhibition of immune responses such as degranulation, phagocytosis, cytokine release, and B cell proliferation. There are three classes of Fc gamma Rs, based on close relationships in their extracellular domains: Fc gamma RI/CD64, Fc gamma RII/CD32, and Fc gamma RIII/CD16. Each group may be encoded by multiple genes and exists in different isoforms depending on species and cell type (1-3). Fc gamma RIII has two isoforms, Fc gamma RIIIA and Fc gamma RIIIB. Fc gamma RIII, the only Fc gamma R found on natural killer cells, is also expressed on macrophages, neutrophils, and mast cells (1-3). Unlike Fc gamma RI which binds IgG with high affinity, Fc gamma RIIIA is a low affinity receptor that recognizes IgG as aggregates surrounding multivalent antigens during late immune responses (4, 5). The mature protein consists of an extracellular domain (ECD), a transmembrane segment, and a cytoplasmic domain. Within the ECD, rat Fc gamma RIIIA shares 83% and 63% amino acid sequence identity with mouse and human Fc gamma RIIIA, respectively.
