The monoclonal antibody is directed against the CD19- antigen (B4-antigen), which is expressed on human B lymphocytes. The monoclonal antibody is B lineage-specific and reacts with early B-cell precursors, pre-pre-B-cells, pre-B- cells, B-cells, intermediate B-cells, mature B-cells and some plasmacytoid cells

Target	CD19
Reactivity	Human
Host	Mouse
Clonality	Monoclonal
Tested Applications	FCM
Recommended dilutions	FCM: 20 μl/1 million cells. Optimal dilutions/concentrations should be determined by the end user.
Immunogen	Human CD19 purified from tonsil.
Purification	Affinity Chromatography
Form	Liquid
Isotype	IgG2a
Conjugation	PE
Specificity	This antibody reacts with the pan-B antigen designated CD19 which appears early during B cell maturation, probably prior to the pre-B cell stage. It is expressed at all stages of B-cell differentiation except terminally differentiated plasma cells. It is also present on the cell surface of follicular dendritic cells.
