Human CD200 ELISA kit is used for quantitative detection of human CD200 in cell culture supernates, serum and plasma (heparin, EDTA).

The protein encoded by this gene is a type-1 membrane glycoprotein, which contains two immunoglobulin domains, and thus belongs to the immunoglobulin superfamily.

CD200-CD200R signaling plays a central role in macrophage fusion and osteoclast formation.
