>Cynomolgus / Rhesus macaque FcRn/FCGRT & B2M Heterodimer Protein
Cynomolgus / Rhesus macaque FcRn Heterodimer Protein (SPR verified), produced by co-expression of FCGRT and B2M, has a calculated MW of 32.3 kDa (FCGRT) and 13.1 kDa (B2M). Subunit FCGRT is fused with a polyhistidine tag at the C-terminus and subunit Beta-2 microglobulin (B2M) is fused with Strep II-tag at the C-terminus. The reducing (R) protein migrates as 36 kDa (FCGRT) and 14 kDa (B2M) respectively due to glycosylation. Cynomolgus / Rhesus macaque FcRn Heterodimer Protein (SPR verified) sequences are identical.
>95% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.
