Invivo Anti-Mouse CD200 (OX2) Recombinant mAb

CD200 (OX2) protein is a type-1 membrane glycoprotein belonging to the immunoglobulin superfamily, widely distributed on various cell types including thymocytes, neurons, endothelial cells, and immune cells such as macrophages and dendritic cells. It plays a crucial role in immune regulation by interacting with its receptor CD200R, which is highly expressed on myeloid cells and some lymphoid cells. The CD200-CD200R interaction inhibits inflammatory responses, promotes immune tolerance, and helps maintain tissue homeostasis. In cancer, CD200 is often overexpressed on tumor cells, contributing to immune evasion by suppressing anti-tumor immune responses. Additionally, elevated levels of soluble CD200 (sCD200) in serum are associated with adverse tumor prognosis in several cancers.
