Human IL-2 R beta&IL-2 R alpha&IL-2 R gamma Protein, His Tag&Twin Strep Tag (MALS verified)

• Background: Both Interleukin-2 receptor subunit beta and Interleukin-2 receptor subunit gamma are receptor for interleukin-2. Common subunit for the receptors for a variety of interleukins. Interacts with SHB upon interleukin stimulation. Probably in association with IL15RA, involved in the stimulation of neutrophil phagocytosis by IL15. This beta subunit is involved in receptor mediated endocytosis and transduces the mitogenic signals of IL2. IL2R exists in 3 different forms: a high affinity dimer, an intermediate affinity monomer (beta subunit), and a low affinity monomer (alpha subunit). The high and intermediate affinity forms also associate with a gamma subunit.
• Description: Human IL-2RB&IL-2RA&IL-2RG, His Tag&Twin Strep Tag (ILG-H52W9) is expressed from human 293 cells (HEK293). It contains AA Ala 27 - Asp 239 (IL-2RB) & Glu 22 - Ser 212 (IL-2RA) & Leu 23 - Asn 254 (IL-2RG) (Accession # P14784-1 (IL-2RB) & P01589-1 (IL-2RA) & P31785-1 (IL-2RG)).
• Specifications: Human 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 29.9 kDa (IL-2RB) & 55.8 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 protein migrates as 37 kDa,42 kDa and 90 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
