Cluster of Differentiation 244 (CD244), 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 (Met 1-Arg221) of human CD244 (NP_057466.1) precursor fused to the Fc region of human IgG1 at the C-terminus.

Activity: Measured by its binding ability in a functional ELISA.
1. Immobilized human CD48 at 10 µg/ml (100 µl/well) can bind recombinant human CD244 with a linear range of 0.004-0.4 µg/ml.
2. Measured by its ability to bind biotinylated mouse CD48 in a functional ELISA.

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.

This protein is manufactured by SINO Biological.
