Optimized DNA sequence encoding Human Fibroblast growth factor binding protein- FGFBP1 (LYS24 - CYS234) extracellular domain including a C-terminal His tag was expressed in HEK293 cells.

Molecular weight:

Recombinant Human FGF binding protein 1(FGF-BP1) is a protein consisting of 217 amino acid residue subunits,due to glycosylation migrates as an approximately as 35kDa band protein on reduced SDS-PAGE.

>95%, as determined by SDS-PAGE and HPLC
Biological Activity
The activity was determined by the ability of FGFBP1 to bind recombinant human bFGF. The ED50 was calculated to be 10-50ng/ml
Endotoxin content was assayed using a LAL gel clot method.
Endotoxin level was found to be less than 0.1 ng/µg(1EU/µg).

Recombinant human Fibroblast growth factor binding protein (FGF-BP1) is lyophilized  from 0.2 μm filtered PBS solution,  pH7.2 ,  5% Trehalose.

A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.

Recombinant Human FGFBP1 can be stored in working aliquots at 2° - 8° C for one month, or at -20°C to -70°C for twelve months.

Avoid repeated freeze/thaw cycles.

Fibroblast growth factor binding protein

Fibroblast growth factor- binding protein (FGF-BP) 1 is a secreted protein that can bind fibroblast growth factors (FGFs) 1 and 2. These FGFs are typically stored on heparan sulfate proteoglycans in the extracellular matrix in an inactive form, and it has been proposed that FGF-BP1 functions as a chaperone molecule that can mobilize locally stored FGF and present the growth factor to its tyrosine kinase receptor. FGF-BP1 is up- regulated in squamous cell, colon, and breast cancers and can act as an angiogenic switch during malignant progression of epithelial cells. Studies with FGF-BP1- negative cell lines showed that expression of FGF-BP1 increased tumor growth and angiogenesis in a nude mouse model. Complementary to that, depletion of endogenous FGF-BP1 from human squamous cell carcinoma and colorectal cancer cell lines reduced their tumor growth and angiogenesis.
