Active Recombinant Human IL2RA

• Cat.No.: IL2RA-4951H
• Product Overview: Recombinant Human IL2RA was expressed in insect cells.

Specification

• 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.
• Source: Insect cells
• Species: Human
• Form: Lyophilized from PBS. Reconstitute with PBS, pH 7.2 to a concentration of 0.1 - 1.0 mg/ml.
• Bio-activity: Determined by its ability to increase the proliferation effect of IL-2 in Mouse CTLL-2 cells. In the presence of 1 ng/ml of recombinant IL-2, the expected ED50 for this effect is between 0.5 - 1.5 ug/ml.
• Molecular Mass: 31 kDa
