Product Summary

The Quantikine HS Human FGF basic Immunoassay kit is a 5.5 hour solid phase ELISA designed to measure FGF basic levels in serum, plasma, and urine. It contains E. coli-expressed recombinant human FGF basic and antibodies raised against the recombinant factor. It has been shown to quantitate recombinant human FGF basic accurately. Results obtained using natural human FGF basic showed linear curves that were parallel to the standard curves obtained using the Quantikine HS kit standards. These results indicate that this kit can be used to determine relative mass values for natural human FGF basic.


Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in separate assays to assess inter-assay precision

Background: FGF basic/FGF2/bFGF

FGF basic/FGF2/bFGF 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/FGF2/bFGF binds to FGFR1c and 2c. Its bioactivity is modulated by a number of other binding partners including heparin, Integrin alpha V beta 3, soluble FGFR1, 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/FGF2/bFGF with cell surface heparan sulfate proteoglycans (HSPG) is required for the binding and activation of FGF receptors.
