Recombinant Human CD55 Protein,His Tag

Description :
Source Recombinant Human CD55 Protein is expressed from HEK293 with His tag at the C-terminal. It contains Asp35-Ser353.[Accession |P08174-1] Molecular Weight The protein has a predicted MW of 35.8 kDa. Due to glycosylation, the protein migrates to 70-75 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 CD55, His Tag at 0.2g/ml (100l/well) on the plate. Dose response curve for Anti-CD55 Antibody, hFc Tag with the EC50 of 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.
