Active Recombinant Human FGFR2 protein(Met1-Glu377), His&hFc-tagged

Specification :
| Source : HEK293 | Species : Human | Tag : C-His&hFc | Protein length : Met1-Glu377 | Form : Lyophilized from sterile PBS, pH 7.4. Normally 5 % – 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. | Bio-activity : Measured by its ability to inhibit FGF-acidic (aFGF/FGF1) dependent proliferation of Balb/C 3T3 mouse fibroblasts. The ED50 for this effect is typically 0.5-2.5 ng/ml. | Molecular Mass : The recombinant human FGFR2/Fc is a disulfide-linked homodimer after removal of the signal peptide. The reduced monomer consists of 604 amino acids and has a predicted molecular mass of 67.6 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rhFGFR2/Fc monomer is approximately 110-120 kDa due to glycosylation. | Endotoxin : | Purity : > 90 % as determined by SDS-PAGE | Storage : Samples are stable for up to twelve months from date of receipt at -20°C to -80°C. Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles. | Reconstitution : It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
