Interleukin 2 Receptor Alpha (IL2RA), recombinant human protein is supplied as a lyophilized powder. It is suitable for use in protein studies such as protein structure analysis and protein-protein interactions. In general, recombinant proteins can also be used as an immunogen, as a protein standard, or in cell biology research applications.

This recombinant protein was expressed from a DNA sequence encoding the extracellular domain of human IL2 receptor α (NP_000408.1) (Met 1-Cys 213) fused to a C-terminal polyhistidine tag.

Activity: Measured by Octet RED System, the affinity constant (Kd) of Human IL2RA-his (Cat:10165-H08H) bound to Human IL2 was 35 nM.

Formulation: Lyophilized in PBS, pH 7.4, 5% Mannitol, 5% Trehalose, 0.02% Tween 80.

Reconstitution: Dissolve the protein in sterile double distilled water to a concentration of 0.2 mg/ml or lower. It is recommended that the protein be aliquoted and be used as soon as possible. Store aliquots under sterile conditions at -20°C. Avoid repeated freeze-thaw cycles.

This protein is manufactured by Sino Biological Inc.
