Interleukin 2 receptor, alpha (IL2RA/CD25), recombinant human protein is supplied as a lyophilized powder. In general, recombinant proteins can be used as protein standard and in cell biology research applications.

This recombinant protein was expressed from a DNA sequence encoding the amino acid residues (Met 1-Cys 213) of the human IL2RA precursor (NP_000408.1) fused to the human IgG1 Fc region at the C-terminus.

Activity: This recombinant protein has not been tested.

Formulation: Lyophilized in PBS, pH7.4, 5% Mannitol, 5% Trehalose, and 0.02% Tween-80.

Reconstitution: Dissolve the protein in sterile double distilled water to a concentration of 25 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.

Expiration Date: Expires one year from date of receipt when stored as instructed.
