MUM1 Protein (Autostainer Link 48)

Labels MUM1 protein in a subset of light zone germinal centre (GC) B cells (probably centrocytes and their progeny), plasma cells and activated T cells. Antibodies to MUM1 protein are a useful aid for classification of a wide spectrum of hematolymphoid neoplasms derived from these cells. Of non-hematolymphoid neoplasms only a proportion of melanomas are labeled (1, 2). Antibodies to MUM1 protein are a useful aid for subclassification of B-cell lymphomas (1-3).
