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.


Formulation Lyophilized from a 0.2 μm filtered solution in PBS.
Reconstitution Reconstitute at 100 μg/mL in sterile PBS.
Shipping The product is shipped at ambient temperature. Upon receipt, store it immediately at the temperature recommended below.
Stability & Storage: Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
  • 12 months from date of receipt, -20 to -70 °C as supplied.
  • 1 month, 2 to 8 °C under sterile conditions after reconstitution.
  • 3 months, -20 to -70 °C under sterile conditions after reconstitution.

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 human CD2F-10 is a type I transmembrane glycoprotein that consists of a 218 amino acid (aa) extracellular domain (ECD) with 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 aa 19-210, human CD2F-10 shares 57% and 59% aa sequence identity with mouse and rat CD2F-10, respectively. Alternative splicing of human CD2F-10 generates an isoform that lacks the Ig-like C2-set domain. CD2F-10 is expressed in hematopoietic tissues and cell lines (3). R&D in house data indicate that CD2F-10 inhibits the secretion of IL-2 from activated human T cells.
