Pro143 - Ser288
>97%, by SDS-PAGE under reducing conditions and visualized by silver stain
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.
For a stock solution, reconstitute at 50 μg/mL in sterile PBS, or simply roll ProDot directly into cell culture medium for immediate use.

ProDots® Recombinant Human FGF basic stimulates cell proliferation of the NR6R-3T3 mouse fibroblast cell line. The ED50 for this effect is 0.1-0.6 ng/mL.
1 μg/lane of ProDots® Recombinant Human FGF basic was resolved with SDS-PAGE under reducing (R) and non-reducing(NR) conditions and visualized with silver staining, showing a single band at 17 kDa.
Background: FGF basic
FGF basic (FGF-2) is a growth factor that functions in angiogenesis, wound healing, tissue repair, learning and memory, and the morphogenesis of heart, bone, and brain. It is upregulated in response to inflammatory stimuli and in many tumors. FGF basic binds to FGF R1c and 2c. Its bioactivity is modulated by a number of other binding partners including heparin, Integrin alpha V beta 3, soluble FGF R1, FGF-BP, free gangliosides, Thrombospondin, Pentraxin 3/TSG-14, Fibrinogen, alpha 2-Macroglobulin, PDGF, and CXCL4/PF4. These molecules act as cellular coreceptors or adhesion partners, extracellular matrix decoys or reservoirs, and soluble scavengers or chaperones. In particular, the interaction of FGF basic with cell surface heparan sulfate proteoglycans (HSPG) is required for the binding and activation of FGF receptors.
What receptors does FGF basic bind?
FGF receptor specificity has been reviewed in multiple citations. Please find more information at: //www.rndsystems.com/resources/articles/fibroblast-growth-factors-and-their-receptors
Does human FGF basic show activity on mouse cells?
Yes, it does. The bioassay uses NR-6 mouse fibroblast cells. There is 95% homology between the human and mouse protein and 98% homology between the human and mouse receptor.
