Recombinant Rat Interleukin 2 Receptor, Alpha

Cat. No.: Il2ra-474R
Product Overview: Recombinant Ratll2ra protein was expressed in Chinese Hamster Ovary cell line, CHO-derived. Glu22- Gln235.
Description: Il2ra, also known asCD25, is a 55 kDa type I membrane glycoprotein that belongs to the family ofcytokine receptors that utilize the common gamma chain subunit (γc). Il2ra isprimarily expressed on activated T cells and on regulatory T cells (Treg). Therat Il2ra cDNA encodes a 267 amino acid (aa) precursor that includes a 21 aasignal peptide, a 214 aa extracellular domain (ECD) with two Sushi domains, a21 aa transmembrane segment, and an 11 aa cytoplasmic domain. Within the ECD,rat Il2ra shares 58% and 81% aa sequence identity with human and mouse IL2 Rα,respectively. It shares approximately 15% aa sequence identity with IL4, 7, 9,15, and 21 receptor subunits that also complex with γc.
Source: Chinese HamsterOvary cell line, CHO-derived.
Form: Lyophilized from a0.2 μm filtered solution in PBS.
N-terminalSequence: Glu22
MolecularWeight: 51.6 kDa (monomer)
Activity: Measured by itsability to inhibit the IL2dependent proliferation of MO7e human megakaryocyticleukemic cells. Avanzi, G. et al. (1988) Br. J. Haematol. 69:359. The ED50for this effect is typically 0.35 1.4 μg/mL in the presence of 30 ng/mL of rhIL2.
Endotoxin Level: <1.0 EU per 1 μgof the protein by the LAL method.
Purity: >95%, by SDSPAGE underreducing conditions and visualized by silver stain.
Reconstitution: Reconstitute at 500μg/mL in sterile PBS.
Storage: Use amanual defrost freezer and avoid repeated freezethaw cycles. 12 months from date of receipt, -20 to -70°C as supplied.1 month, 2 to 8 °C under sterile conditions after reconstitution. 3months, -20 to -70°C under sterile conditions after reconstitution.
