Fc gamma receptor II-a (FCGR2A/CD32a), recombinant human protein is supplied as a lyophilized powder. It is suitable for use in analysis of protein structure. 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 (Met 1-Gly 216) of human FCGR2A precursor (AAH19931.1) fused to a polyhistidine tag at the C-terminus.

Activity: This recombinant protein has not been tested.

Formulation: Lyophilized in 20 mM Tris buffer, 50 mM NaCl, pH 7.4. Contains 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.
