蛋白结构（Molecular Characterization）

Cynomolgus IL-2RB&IL-2RA&IL-2RG, His Tag&Twin-Strep Tag is produced by co-expression of IL-2RB and IL-2RA and IL-2RG, has a calculated MW of 30.1 kDa (IL-2RB) and 55.9 kDa (IL-2RA&IL-2RG). Subunit IL-2RB is fused with a his tag at the C-terminus and subunit IL-2RA&IL-2RG is fused with a Twin-Strep Tag at the C-terminus. The reducing (R) protein migrates as 37-44 kDa and 85-100 kDa respectively due to glycosylation.
