Immunohistochemistry analysis of PAX5 showing staining in the nucleus of paraffin-embedded human tonsil tissue (right) compared to a negative control without primary antibody (left). To expose target proteins, antigen retrieval was performed using 10mM sodium citrate (pH 6.0), microwaved for 8-15 min. Following antigen retrieval, tissues were blocked in 3% H2O2-methanol for 15 min at room temperature, washed with ddH2O and PBS, and then probed with a Anti- PAX5 Polyclonal Antibody (ZP007) (396800) diluted in 3% BSA-PBS at a dilution of 1:100 overnight at 4°C in a humidified chamber. Tissues were washed extensively in PBST and detection was performed using an HRP-conjugated secondary antibody followed by colorimetric detection using a DAB kit. Tissues were counterstained with hematoxylin and dehydrated with ethanol and xylene to prep for mounting.

PAX-5 is a B-cell-specific activator protein (BSAP). In the early stages of B cell developmemt, PAX-5 influences the expression of several B-cell-specific genes, such as CD19 and CD20. PAX-5 is expressed primarily in pro-, pre-, and mature B cells, but not in plasma cells. PAX-5 is expressed in most B-cell malignancies (pre-B and mature B cell lymphomas/leukemias). Over 90% of cases are positive for PAX-5 in Hodgkin's lymphoma, lymphoplasmacytic lymphoma, Merkel cell and small cell carcinoma. T-cell lymphomas, myeloma/plasmacytoma and carcinoid tumors are negative for PAX-5.
