Recombinant Human CD8 alpha/CD8A Protein,His Tag

Description :
Synonyms CD8;MAL;Lyt-2;CD8a Source Human CD8 alpha/CD8a Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Ser22-Asp182.[Accession | P01732-1] Molecular Weight The protein has a predicted MW of 18.70 kDa. Due to glycosylation, the protein migrates to 28-35 kDa based on SDS-PAGE result. 内毒素Endotoxin Less than 1EU per g by the LAL method. Purity > 95% as determined by SDS-PAGE Activity ELISA Data: Immobilized Human CD8 alpha, His Tag at 1g/ml (100l/well) on the plate. Dose response curve for Anti-CD8 Antibody, hFc Tag with the EC50 of 29.4ng/ml determined by ELISA. Formulation Lyophilized from 0.22 m filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. Reconstitution Centrifuge the tube before opening. Reconstituting to a concentration more than 100 g/ml is recommended. Dissolve the lyophilized protein in distilled water.
