BOB-1 Immunostain, Technical Component Only
Use
BOB-1 is a transcriptional co-activator that interacts with transcription factors OCT-1 or OCT-2, regulating transcription of immunoglobulin genes. In normal tonsil tissue, germinal center B cells express BOB-1, with scattered expression in the mantle zone. Expression of BOB-1, OCT-2, and PU.1 transcription factors are down-regulated in classic Hodgkin lymphomas, unlike many diffuse large B-cell lymphomas.
