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). Results aid in the classification of B-lineage leukemias and lymphomas.

Specificity
In Western blotting of lysed Raji cells (Burkitt's lymphoma) and Jurkat cells (T-ALL) under reduced conditions, the antibody labels a band of 95 kDa in Raji cells, corresponding to CD19, whereas no band is observed in Jurkat cells.
The focus of the sixth edition of the IHC Guidebook is to provide a comprehensive immunohistochemistry (IHC) resource for lab managers, lab technicians, learning pathologists, and students from around the world.
