Analysis
Product Datasheets
Carrier Free
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.
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: CD2F-10/SLAMF9
The CD2 family of receptors is a subset of the immunoglobulin superfamily of glycoproteins. The CD2F‑10 protein, also known as SF2001 and CD85‑H1, was identified as a CD2 subfamily member using genome sequence data. Based on its structural organization, CD2F‑10 belongs to the SLAM (Signaling Lymphocyte Activation Molecule) subfamily of CD2 receptors and is designated SLAMF9. SLAM proteins function as co‑receptors for lymphocyte activation and/or adhesion (1). Mature mouse CD2F‑10 is a type I transmembrane glycoprotein that consists of a 215 amino acid (aa) extracellular domain (ECD) with one Ig‑like V‑set and one Ig‑like C2‑set domain, a 21 aa transmembrane segment, and a 32 aa cytoplasmic domain (2 ‑ 4). Unlike other SLAM proteins, the cytoplasmic domain of CD2F‑10 does not contain consensus immunoreceptor tyrosine‑based switch motifs (ITSMs) that mediate interactions with the signal transduction proteins SAP or EAT‑2 (1). Within the ECD, mouse CD2F‑10 shares 58% and 83% aa sequence identity with human and rat CD2F‑10, respectively. It shares 21% ‑ 38% aa sequence identity with comparable regions of mouse 2B4, BLAME, CD48, CD84, CD229, CRACC, NTB‑A, and SLAM. CD2F‑10 is expressed in hematopoietic tissues and cell lines (3). R&D in house data indicate that CD2F‑10 costimulates the secretion of IFN‑ gamma from activated mouse T cells.
