Recombinant Mouse IL2RA Protein (Glu22-Lys236), C-10×His-tagged
Product Description
Cat
IMP-10534
Official Symbol
Il2ra
Product Overview
Recombinant Mouse CD25/IL-2R alpha protein (Glu22-Lys236) with a C-terminal 10-His tag was expressed in Mouse myeloma cell line.
Description
The interleukin 2 (IL2) receptor alpha (IL2RA) and beta (IL2RB) chains, together with the common gamma chain (IL2RG), constitute the high-affinity IL2 receptor. Homodimeric alpha chains (IL2RA) result in low-affinity receptor, while homodimeric beta (IL2RB) chains produce a medium-affinity receptor. Normally an integral-membrane protein, soluble IL2RA has been isolated and determined to result from extracellular proteolyisis. Alternately-spliced IL2RA mRNAs have been isolated, but the significance of each is presently unknown. Mutations in this gene are associated with interleukin 2 receptor alpha deficiency. Patients with severe Coronavirus Disease 2019 (COVID-19), the disease caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), have significantly elevated levels of IL2R in their plasma. Similarly, serum IL-2R levels are found to be elevated in patients with different types of carcinomas. Certain IL2RA and IL2RB gene polymorphisms have been associated with lung cancer risk.

Bio-activity
Measured by its ability to inhibit the IL-2-dependent proliferation of MO7e human megakaryocytic leukemic cells. The ED50 for this effect is 0.045-0.3 μg/mL in the presence of 30 ng/mL of recombinant human IL-2.
Endotoxin
<1.0 EU/μg of the protein by the LAL method.
Purity
>95%, by SDS-PAGE under reducing conditions and visualized by silver stain.
Storage
12 months from date of receipt, ≤ -20 centigrade as supplied.
1 month, 2 to 8 centigrade under sterile conditions after reconstitution.
3 months, ≤ -20 centigrade under sterile conditions after reconstitution.
Reconstitution
Reconstitute at 100 μg/mL in sterile PBS.
