Recombinant Human FGF-BP Protein, CF Summary
1 μg/mL of rhFGF-BP was mixed with serially diluted rhFGF basic (Catalog # 233-FB). Following incubation, the FGFBP-FGF basic complex was captured on a Gt x hFGFBP-coated plate. Bound FGF basic was measured using biotinylated Gt x hFGF basic. The concentration of rhFGF basic that produces 50% of the optimal binding was found to be approximately 5-20 ng/mL.
Lys24-Cys234 & Asn29-Cys234 both with a C-terminal 10-His tag
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.

Fibroblast growth factor binding protein (FGF-BP), also known as HBp17, is a secreted glycoprotein that increases the bioavailability of FGFs (1). Mature FGF-BP is a 34 kDa, 211 amino acid (aa) O-glycosylated protein with five conserved intrachain disulfide bonds (2 - 4). FGF-BP contains a heparin-binding domain (aa 110 - 143) and a distinct FGF-binding region (aa 193 - 243) (5). Mature human FGF-BP shares 59% and 54% aa sequence identity with mouse and rat FGF-BP, respectively. FGF-BP is expressed throughout development and in adult squamous epithelium (2, 6). It is upregulated in injured skin, renal tubular epithelium, and spinal nerves as well as in carcinomas of the skin, colon, and pancreas (3, 7 - 10). FGF-BP binds FGF-1, -2, -7, -10, and -22 which are secreted and sequestered in the extracellular matrix (ECM) (7, 11). The association of FGF-BP with heparan sulfate proteoglycans (HSPG) weakens HSPG attachment of FGFs and promotes their release (2, 8, 12, 13). FGF-BP enhances the mitogenic effects of FGFs, thereby contributing to epithelial, endothelial, and neuronal tissue repair, angiogenesis, and tumor growth (7 - 9, 11, 14, 15).
