Cat#:RP-1703H;Product Name:Recombinant Human FCGRT & B2M Heterodimer Protein;Synonym:alpha-chain,FCRN;Description:A DNA sequence encoding the extracellular domain (Met 1-Ser 297) of human FCGRT (P55899) was fused with a polyhistidine tag at the C-terminus, constructed the plasmid 1; A DNA sequence encoding the human B2M (P61769) (Met 1-Met 119) constructed the plasmid 2. The two plasmids were co-expressed and the FCGRT / B2M heterodimer was purified.;Source:Human Cells;Predicted N Terminal:Ala 24 & Ile 21;Molecular Characterization:The recombinant heterodimer of human FCGRT/B2M comprises 385 (285 + 100) amino acids and has a calculated molecular mass of 43.5 (31.8 + 11.7) kDa. The apparent molecular mass of rh FCGRT/B2M heterodimer is approximately 35 & 12 kDa respectively in SDS-PA;Purity:Greater than 95 % 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 PBS, pH 7.4;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℃).;
