Recombinant Human Fc epsilon RI alpha/FCER1a Protein,hFc Tag

Description :
Source Human Fc epsilon RI alpha/FCER1a Protein is expressed from HEK293 with hFc tag at the C-terminal. It contains Val26-Gln205.[Accession |P12319-1] Molecular Weight The protein has a predicted MW of 47.8 kDa. Due to glycosylation, the protein migrates to 70-78 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 PAGEand HPLC Activity ELISA Data: Immobilized Human Fc epsilon RI alpha, hFc Tag at 0.5g/ml (100l/Well) on the plate. Dose response curve for Biotinylated Anti-Fc epsilon RI alpha Antibody, hFc Tag with the EC50 10ng/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.
