CD48 Antibody, anti-human, APC

Identification and enumeration of CD48+ cells by flow cytometryClone REA426 recognizes the human CD48 antigen, a glycosyl-phosphatidyl-inositol (GPI)-anchored cell-surface protein of the CD2 family of molecules, which is also known as B-lymphocyte activation marker BLAST-1, BCM1, MEM-102, or SLAM family member 2 (SLAMF2). CD48 is expressed on various hematopoietic cells and its expression is regulated by viral and bacterial products and immune-associated proteins. CD48 binds CD2 and other molecules, yet its high-affinity ligand in both mouse and human systems is CD244 (2B4). Despite its lack of an intracellular domain, stimulation of CD48 induces rearrangement of signaling factors in lipid rafts, Lck-kinase activity, and tyrosine phosphorylation. As an adhesion and co-stimulatory molecule, CD48 induces numerous effects in B and T lymphocytes, natural killer cells, mast cells, and eosinophils. Some of these depend upon cell-cell interactions via CD244-CD48 binding. | Additional information: Clone REA426 displays negligible binding to Fc receptors.
