CD19 Antibody, anti-mouse, APC

01MT16619

Clone 6D5 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.
