Cat#:RP-1620M;Product Name:Recombinant Mouse FCGRT & B2M Heterodimer Protein;Synonym: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 i;Purity:Greater than 95 % as determined by SDS-PAGE;Endotoxin: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: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℃).;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 -88℃).;
