>Porcine FcRn/FCGRT & B2M Heterodimer Protein
Porcine FcRn / FCGRT & B2M heterodimer protein, produced by co-expression of FCGRT and B2M, has a calculated MW of 32.3 kDa (FCGRT) and 12.8 kDa (B2M). Subunit FCGRT is fused with a polyhistidine tag at the C-terminus and subunit Beta-2 microglobulin (B2M) is fused with a Strep II tag at the C-terminus. The predicted N-terminus is Asp 16 (FCGRT) & Val 21 (B2M). The reducing (R) protein migrates as 36 kDa (FCGRT) and 15 kDa (B2M) respectively.
>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.
