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).

Precursor B-cell lymphoblastic leukemia/lymphoma (FFPE) stained with FLEX Anti-CD19, Code IR656/IS656.

Precursor B-cell lymphoblastic leukemia/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.

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.

Tonsil. The B cells in the mantle zone and in the germinal center show a moderate to strong membranous staining reaction. No staining should be seen in the epithelial cells.

Recommended control for IR656/IS656. Appendix/Colon/Tonsil.

Colon. The plasma cells in the lamina propria show a weak to moderate membranous staining reaction.

Recommended control for IR656/IS656. Appendix/Colon/Tonsil.

Lymphoma stained with Anti-CD19.

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