Recombinant Human FGFR2 beta (IIIb) Domain Protein,hFc Tag

Description :
Source Human FGFR2 beta (IIIb) Domain Protein is expressed from HEK293 with hFc tag at the C-terminal. It contains Pro253-Glu378.[Accession |P21802-3] Molecular Weight The protein has a predicted MW of 40.5 kDa. Due to glycosylation, the protein migrates to 60-68 kDa based on Tris-Bis PAGE result. 内毒素Endotoxin Less than 1EU per g by the LAL method. Purity > 95% as determined by Tris-Bis PAGEandHPLC Activity ELISA Data: Immobilized Human FGFR2 beta (IIIb) Domain, hFc Tag at 0.5g/ml (100l/Well) on the plate. Dose response curve for Biotinylated Anti-FGFR2 (IIIb) Antibody,hFc Tag with the EC50 14.3ng/ml determined by ELISA. Formulation Lyophilized from 0.22m filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. Reconstitution Centrifuge tubes before opening. Reconstituting to a concentration more than 100 g/ml is recommended. Dissolve the lyophilized protein in distilled water.
