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: VEGF
The human VEGF-A gene contains eight exons plus a nontraditional ninth exon in the 3’ UTR (1). The A gene gives rise to multiple splice variants of VEGF-A, ranging from 121 amino acids (aa) to 206 aa in length. All human splice variants contain exons 1-5 and some part of exon 8. Exons 6 and 7 are split into at least two parts, some of which may be included in any one molecule (1-5). The nontraditional 9th exon is a substitute for exon 8. Incorporation of the 9th exon results in a non-signaling form of VEGF (5). VEGF162 is a VEGF isoform that induces endothelial cell proliferation in vitro and angiogenesis in vivo (5). It is synthesized as a 40-45 kDa disulfide-linked homodimer whose subunits are a product of exons 1-5, 6a, 6b and 8 (5). The three aa difference between VEGF165 and VEGF162 is attributable to the fact that the 165 form only utilizes exon 7 while the 162 form only utilizes exon 6. Within exon 6, exon 6a contributes 24 aa while exon 6b contributes 17 aa (aa 116‑156 in the mature segment) (2). Exon 6a is not commonly found with exon 6b. In VEGF162, exon 6b appears to act as a counterpart to the activity of exon 6a. That is, the product of exon 6a normally promotes VEGF binding to basement membrane while the product of exon 6b promotes VEGF dissociation and solubilization. In this case, VEGF162 is notably soluble.
