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: IL-17RA/IL-17R

Interleukin 17 (also known as CTLA‑8) is a T cell‑expressed pleotropic cytokine. IL‑17 binds to IL‑17 receptor (IL‑17 R) which shares no homology with any known family of receptors. While the expression of IL‑17 is restricted to activated T cells, the IL‑17 R mRNA exhibits a broad tissue distribution, and has been detected in virtually all cells and tissues tested. The human IL‑17 R gene was localized to chromosome 22. Human IL‑17 R is an 866 amino acid (aa) type I membrane glycoprotein with a 293 aa extracellular domain, a 21 aa carboxy‑proximal transmembrane domain, and a 525 aa cytoplasmic tail. The aa sequence of human IL‑17 R is 69% identical to the mouse IL‑17 R. The signaling events of IL‑17 includes activation of NF‑ kappa B and JNK, and require TNF receptor‑associated factors 6 (TRAF6) in the signaling pathway.
