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

Description :
Source Recombinant Human Fc epsilon RI alpha/FCER1a Protein is expressed from HEK293 with His tag at the C-terminal. It contains Val26-Gln205.[uniprot |P12319-1] Molecular Weight The protein has a predicted MW of 22.1 kDa. Due to glycosylation, the protein migrates to 48-65 kDa based on Tris-Bis PAGE result. 内毒素Endotoxin Less than 1EU per ug by the LAL method. Purity > 95% as determined by Tris-Bis PAGEandHPLC Activity ELISA Data: Immobilized Human Fc epsilon RI alpha, His Tag at 0.2g/ml (100l/well) on the plate. Dose response curve for Anti-Fc epsilon RI alpha Antibody , hFc Tag with the EC50 of 14.1ng/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.
