Synonyms

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

Source

Rat IL-2RB&IL-2RG Heterodimer Protein, His Tag&Twin-Strep Tag (ILG-R5283) is expressed from human 293 cells (HEK293). It contains AA Ala 27 - Glu 239 (IL-2RB) & Ser 25 - Ala 262 (IL-2RG) (Accession # P26896-1 (IL-2RB) & Q68FU6-1 (IL-2RG)).

Predicted N-terminus: Ala 27 (IL-2RB) & Ser 25 (IL-2RG)

Molecular Characterization

Rat 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 30.2 kDa (IL-2RB) and 34.7 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 reducing (R) protein migrates as 40-50 kDa and 55-65 kDa respectively due to glycosylation.
