CD19 antibodies, mouse

Clone: REA749 | Dilution: 1:50
Clone REA749 recognizes the mouse CD19 antigen, a type I transmembrane glycoprotein expressed on B cells throughout their development from the early pro–B cell through the mature B cell stages. Its expression is down-regulated during terminal differentiation to plasma cells. CD19 associates with complement receptor CD21 and with CD81 on the cell surface of mature B cells, thereby forming a multi-molecular complex which signals synergistically to membrane IgM. It is also expressed on follicular dendritic cells and peritoneal mast cells.
Additional information: Clone REA749 displays negligible binding to Fc receptors.
