Heat-mediated antigen retrieval is recommended prior to staining, using an EDTA buffer, pH 8.0, for 10 minutes followed by cooling at room temperature for 20 min. Following antigen retrieval, incubate samples with primary antibody for 30 min at room temperature. A suggested positive control is tonsil tissue.
CD19 is expressed in B lymphocytes and B-cell lymphoma. It may also be present on some early myeloid progenitors, particularly those of the monoblastic type. It appears to be expressed on myeloid leukemia cells, particularly those of monocytic lineage. Leukemia phenotype studies have demonstrated that the earliest and broadest B cell restricted antigen is the CD19 antigen. CD19 is negative in T lymphocytes, plasma cells, and their tumors.
