Recombinant Human CEACAM-5/CD66e (501-685) Protein,His Tag

Description :
Synonyms CEA;Carcinoembryonic;CD66e;CEACAM-5 Source Human CEACAM-5/CD66e (501-685) Protein is expressed from HEK293 with His tag at the C-terminus. It contains Pro501-Ala685.[Accession | P06731-1] Molecular Weight The protein has a predicted MW of 20.89 kDa. Due to glycosylation, the protein migrates to 50-70 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 Human CEACAM-5, His Tag at 2g/ml (100l/well) on the plate. Dose response curve for Anti-CEACAM5 Antibody, hFc Tag with the EC50 of 28.8ng/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.
