Formulation, Preparation and Storage
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: CXCL7/Thymus Chemokine-1
CXCL7 is a member of the alpha (CXC) subfamily of chemokines. Rat CXCL7 cDNA encodes a 111 amino acid residue precursor protein. Rat CXCL7 shares 72% amino acid sequence identity with mouse CXCL7 (accession number AAG36786). The recombinant rat CXCL7 produced by R&D Systems has been shown to chemoattract human CXCR2 transfected mouse BaF/3 cells, but not human CXCR1 transfected mouse BaF/3 cells.
