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: VEGF

VEGF189 (Vascular Endothelial Growth Factor-A of 189 amino acids) is a 50-52 kDa homodimeric glycoprotein member of the PDGF/VEGF family of molecules (1, 2). A large number of human VEGF isoforms are generated by alternative splicing, including VEGF189 which lacks amino acids (aa) 166-182 of the full length protein (VEGF206) (3-5). Mature human VEGF189 shares 88% aa sequence identity with mouse VEGF188. VEGF189 binds to heparan sulfate both on the cell surface and in the extracellular matrix (ECM) where it retains bioactivity (6, 7). It can undergo proteolytic cleavage from the ECM (at Arg136-Ala137), creating a soluble fragment with increased bioactivity (6, 7). VEGF189 is widely expressed including by vascular smooth muscle cells (3), chondrocytes (8), fibroblasts (9), neuronal and glial cells (10), and neutrophils (11). VEGF189 interacts with various receptors including VEGF R1, VEGF R2, Neuropilin-1, and Integrins aVb3, aVb5, a3b1, and a5b1 (6, 12-14). VEGF189 exerts complex effects in angiogenesis. It is proapoptotic towards quiescent vascular endothelium but is proangiogenic towards endothelium that has committed to the angiogenic process (6, 14). In particular, venous endothelial cells are highly responsive towards VEGF189, while the responsiveness of arterial endothelium is primarily restricted to the regulation of migration (7). In addition to its vascular effects,  immobilized VEGF189 serves as an anchor for cells expressing Integrin avb3, and it acts as both a chemotactic and chemokinetic factor for migrating neutrophils (11, 13, 14).
