Summary: Cat.No. : CD81-247H Product Overview : Recombinant Human CD81 (NP_004347.1) (Phe113-Lys201), fused with the Fc region of mouse IgG1 at the N-terminus, was produced in Human Cells. Source : Human Cells Species : Human Tag : Fc Predicted N Terminal : Asp Form : Lyophilized from sterile PBS, pH 7.4.Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Molecular Mass : The recombinant human CD81/mFc comprises 325 amino acids and has a predicted molecular mass of 36.4 kDa. The apparent molecular mass of the monomer is approximately 38-42 kDa in SDS-PAGE under reducing conditions due to glycosylation.
