分子别名（Synonym）

IL-2 R beta & IL-2 R gamma,IL-2RB & IL-2RG

表达区间及表达系统（Source）

Human IL-2RB&IL-2RG Heterodimer Protein, His Tag&Twin-Strep Tag (ILG-H5283) is expressed from human 293 cells (HEK293). It contains AA Ala 27 - Asp 239 (IL-2RB) & Leu 23 - Asn 254 (IL-2RG) (Accession # P14784-1 (IL-2RB) & P31785-1 (IL-2RG)).

Predicted N-terminus: Ala 27 (IL-2RB) & Leu 23 (IL-2RG)

蛋白结构（Molecular Characterization）

Human IL-2RB&IL-2RG Heterodimer Protein, His Tag&Twin-Strep Tag is produced by co-expression of IL-2RB and IL-2RG, has a calculated MW of 29.9 kDa (IL-2RB) and 34.1 kDa (IL-2RG). Subunit IL-2RB is fused with a polyhistidine tag at the C-terminus and subunit IL-2RG is fused with Twin-Strep tag at the C-terminus. The protein migrates as 40-44 kDa and 60-65 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
