Clone REA299 recognizes the mouse CD150 antigen, a 75-95 kD single-pass type I membrane protein also known as signaling lymphocyte activation molecule (SLAM). CD150 belongs to the immunoglobulin superfamily and acts as a self ligand. Expression of CD150 is found on B cells, dendritic cells and activated/memory T cells. It is involved in functions such as stimulation, proliferation and inhibition of apoptosis of B cells, stimulation and IFN-γ production in Th1 T-cell clones and recently it has been identified as the second receptor for measles virus. In combination with CD48 and CD244, CD150 is a useful marker for hematopoietic stem cell studies.

Additional information: Clone REA299 displays negligible binding to Fc receptors.
