Cat#:RP-0336H;Product Name:Recombinant Human CD40 / TNFRSF5 Protein (His & Fc Tag);Synonym:Bp50,CDW40,p50,TNFRSF5;Description:A DNA sequence encoding the human CD40 (NP_001241.1) extracellular domain (Met 1-Arg193) was fused with the C-terminal polyhistidine-tagged Fc region of human IgG1 at the C-terminus.;Source:Human Cells;Predicted N Terminal:Glu 21;Molecular Characterization:The recombinant human CD40/Fc is a disulfide-linked homodimer. The reduced monomer consists of 421 amino acids and has a predicted molecular mass of 47.3 kDa. As a result of glycosylation, the apparent molecular mass of rhCD40/Fc monomer migrates with an ;Purity:Greater than 85 % as determined by SDS-PAGE;Endotoxin:< 1.0 EU per ug of the protein as determined by the LAL method;Bioactivity:Please contact us for detailed information;Formulation:Lyophilized from sterile 100mM Glycine, 10mM NaCl, 50mM Tris, pH 7.5;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Reconstitution:Please see related COA for specific instructions.;Storage:Avoid repeated freeze-thaw cycles. In lyophilized state for 1 year (4-8℃); Upon reconstitution under sterile conditions for 2 weeks (4-8℃) or 3 months (-20℃ to -70℃).;
