Complement component (3d/Epstein Barr virus) receptor 2 (CR2), 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 CR2 (P20023-1) extracellular domain (Met 1-Arg 971) fused to a polyhistidine tag at the C-terminus.

Activity: Measured by its binding ability in a functional ELISA
. Immobilized human CR2 at 2 µg/ml (100 µl/well) can bind biotinylated human CD9.
The EC50 of biotinylated human CD9 is 1.76 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 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.

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