Tonsil stained with Anti-CD19
CD19 is a pan B cell marker expressed in a wide range of maturational stages including pre B cells. CD19 labels the membrane of B cells in germinal centers including B cells and follicular dendritic cells, mantle zone cells and cells in the interfollicular areas. It is negative in plasma cells. CD19 is found in the majority of B cell-derived malignancies.
