Fibroblast growth factor receptor 1 (FGFR1), recombinant human protein is supplied as a lyophilized powder. It is suitable for use in protein studies such as protein structure analysis and protein-protein interactions. In general, recombinant proteins can also be used as an immunogen, as a protein standard, or in cell biology research applications.

Since this product is a truncated protein and does not contain intracellular catalytic activity domain, it is not suitable for use in enzyme activity studies..

This recombinant protein was expressed from a DNA sequence encoding the extracellular domain (Met 1-Glu 285) of human FGFR1 (NP_075594.1) fused to the polyhistidine-tagged Fc region of human IgG1 at the C-terminus.

Activity: Measured by its ability to inhibit FGF1-dependent proliferation of BALB/c 3T3 mouse fibroblasts. The ED₅₀ for this effect is typically 2-4 ng/ml.

Formulation: Lyophilized in PBS, pH7.4, 5% Mannitol, 5% Trehalose, and 0.02% Tween-80.

Reconstitution: Dissolve the protein in sterile double distilled water to a concentration of 0.2 mg/ml or lower. It is recommended that the protein be aliquoted and be used as soon as possible. Store aliquots under sterile conditions at -20°C. Avoid repeated freeze-thaw cycles.

Expiration Date: Expires one year from date of receipt when stored as instructed.

This protein is manufactured by SINO Biological.
