Synonyms

IL-2 R beta & IL-2 R alpha & IL-2 R gamma

Source

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)).

Predicted N-terminus: Ala 27 & Glu 22

Molecular Characterization

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.

The protein is designed as a heterotrimer.

Endotoxin

Less than 1.0 EU per μg by the LAL method / rFC method.

Purity

>90% as determined by SDS-PAGE.

>95% as determined by SEC-MALS.

Formulation
