Cat#:FCGRT-001HAC;Product Name:Recombinant Human FCGRT & B2M Heterodimer Protein;Synonym:FCGRT, B2M, FcRn, FCRN; alpha-chain;Description:Recombinant Human FCGRT & B2M Heterodimer Protein, Ala 24 - Ser 297 and Ile 21 - Met 119, was produced in HEK293 cells. Recombinant Human FCGRT & B2M Heterodimer Protein was purified using our unique chromatographic techniques.;Source:HEK293;Predicted N Terminal:Ala 24(FCGRT) and Ile 21(B2M);Molecular Characterization:Recombinant Human FCGRT & B2M heterodimer protein, produced by co-expression of FCGRT and B2M, has a calculated molecular weight of 31.2 kDa FCGRT and 13.1 kDa B2M. Subunit FCGRT was fused with his tag at the C terminus and subunit B2M was fused with Strep II tag at the C terminus. The reducing protein migrates as 33 kDa FCGRT and 13 kDa B2M respectively due to glycosylation.;Purity:Greater than 95% as determined by SDS-PAGE.;Endotoxin:< 1.0 EU per ug of human FCGRT protein by the LAL method.;Formulation:Recombinant human FCGRT & B2M Heterodimer protein was lyophilized from 0.22 um filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.;Stability:Recombinant human FCGRT & B2M Heterodimer protein was stable up to 1 year from date of receipt at -70℃;Storage:Store recombinant human FCGRT & B2M Heterodimer protein under sterile conditions at -20℃ to -80℃. It is recommended that the recombinant protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.;Usage:For Lab Research Use Only;
