Monoclonal Mouse Anti-Human

CD19

Clone LE-CD19

CD19 is the broadest lineage-specific surface marker for B cells.

CD19 is present on the surface of virtually all B lymphocytes, including early B-progenitor cells, but it is lost upon terminal differentiation to plasma cells. CD19 is also expressed on follicular dendritic cells (1). B-lineage leukemias and lymphomas rarely lose the CD19 antigen (2).

B-cell chronic lymphatic leukemia (FFPE) stained with FLEX Anti-CD19, Code IR656/IS656.

B-cell chronic lymphocytic leukemia/small lymphocytic lymphoma. The majority of the neoplastic cells show a moderate to strong predominantly membranous staining reaction.

Clinical application for IR656/IS656. For identification of B cells in normal and neoplastic tissue.
