Recombinant Cynomolgus Her2/ErbB2 Protein,His Tag

Description :
Synonyms ErbB2; EGFR2;CD340; HER-2 Source Cynomolgus Her2/ErbB2 Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Thr23-Thr652.[Accession | XP_005584091.2] Molecular Weight The protein has a predicted MW of 70.4 kDa. Due to glycosylation, the protein migrates to 85-105 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 and HPLC. Activity ELISA Data: Immobilized Cynomolgus Her2, His Tag at 0.2g/ml (100l/Well) on the plate. Dose response curve for Anti-Her2 Antibody, hFc Tag with the EC50 of 13.3ng/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 the tube before opening. Reconstituting to a concentration more than 100 g/ml is recommended. Dissolve the lyophilized protein in distilled water.
