Interleukin 3 receptor, alpha (low affinity) (IL3RA), 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 human IL3RA (NP_002174.1) extracellular domain (Met 1-Arg 305) fused to the C-terminal polyhistidine-tagged Fc region of human IgG1 at the C-terminus.

Activity: Measured by its binding ability in a functional ELISA . Immobilized human IL3 at 20 µg/ml (100 µl/well) can bind human IL3RA with a linear range of 0.064-1.6 µg/ml.

Formulation: Lyophilized in 140 mM NaCl, 2.7 mM KCl, 10 mM Na₂HPO₄, 1.8 mM KH₂PO₄, pH 7.4, 5% Mannitol, 5% Trehalose, 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.
