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. Range: 0.31 - 20 pg/mL. Sensitivity: 0.07 pg/mL. Time: 5.5 hours
