Human IL-2RB&IL-2RA&IL-2RG Protein, His Tag&Twin Strep Tag AIDD-Ready protein is designed for direct use in SPR assays. It is supplied in a sugar-free, glycerol-free formulation to eliminate refractive index interference in SPR. No desalting or buffer exchange is required before use, simplifying the SPR workflow and supporting high-throughput experimental validation to accelerate the transition from AI prediction to wet-lab validation.
IL-2 R beta & IL-2 R alpha & IL-2 R gamma
Human IL-2RB&IL-2RA&IL-2RG Protein, His Tag&Twin Strep Tag (ILG-H52W9AI) 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
The protein has a calculated MW of 29.9 kDa (IL-2RB) & 55.8 kDa (IL-2RA&IL-2RG). The protein migrates as 33-35 kDa, 37-38 kDa and 65-85 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.
