Recombinant Human Activin RIIB/ACVR2B Protein,His Tag

Description :
Synonyms Activin RIIB;ACVR2B;Activin receptor type-2B Source Human Activin RIIB/ACVR2B Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Ser19-Thr137.[Accession | Q13705-1] Molecular Weight The protein has a predicted MW of 14.75 kDa. Due to glycosylation, the protein migrates to 25-45 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 Activin A, No Tag at 1g/ml (100l/well) on the plate. Dose response curve for Human Activin RIIB, His Tag with the EC50 of 21.4ng/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.
