Heat-mediated antigen retrieval is recommended prior to staining, using a 10mM EDTA buffer 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 Hodgkin's lymphoma.
The MUM1 (Multiple Myeloma Oncogene 1) gene was originally identified because of its involvement in the t(6;14) translocation observed in multiple myeloma, which causes juxtaposition of the MUM1 gene to the Ig heavy-chain locus. MUM1 is expressed in a wide spectrum of lymphoid neoplasms but not in myeloid and extra-hematopoitic tumors. MUM1 is a valuable marker for understanding and characterizing histogenesis of B-cell lymphomas. It is an excellent marker for Reed-Sternberg cells of classic Hodgkin's disease.
