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: CD200R1L

CD200 Receptor 2 (CD200R2), or CD200R1L, is a type I transmembrane receptor for the CD200 cell surface glycoprotein. Mature CD200R2 consists of an extracellular domain (ECD) containing an Ig-like V-type domain and an Ig-like C2-type domain, a transmembrane segment and a short cytoplasmic domain. The ECD of mouse CD200R2 shares a 76% and 63% amino acid (aa) identity with the rat and human ECD, respectively. CD200R2 is strongly expressed on resting mast cells but deceased upon activation via Fc epsilon R1. It is also observed on monocytes, bone marrow-derived dendritic cells and TH2 cells (1, 2, 4). It has been demonstrated CD200R2 can interact with CD200 (3) and signal through adaptor protein, DAP12, via its lysine residue in the transmembrane region (2). In addition, it has been reported CD200 and CD200R2 interaction alters dendritic cell differentiation and enhances induction of CD4+CD25+Foxp3+ regulatory T cells in mouse transplant model (5).
