| Mouse anti Human CD19 antibody, clone LT19recognizes human CD19 also known as T-cell surface antigen Leu-12 or B-lymphocyte surface antigen B4. CD19 is a ~95 kDa type I single pass transmembrane glycoprotein expressed on follicular dendritic cells and B-cells during maturation but is lost on development into plasma cells (de Rieet al.1989).CD19 is the broadest lineage specific marker for B cells and functions as a B-cell co-receptor in conjunction with CD21 (Bradburyet al.1992), CD9, CD81 and CD82 (Horváthet al.1998). CD19 is implicated in the down-regulation of B cell growth and proliferation (Pezzuttoet al.1987). |
