B细胞特异性转录因子抗体 B Cell Specific Octamer Binding Protein-1 (BOB-1) Clone TG14 7 mL BOND ready-to-use PA0558 P (HIER) Antigen Background B cell specific octamer binding protein-1 (BOB-1), also known as OBF-1 and OCA-B, is a lymphocyte specific transcriptional coactivator protein. It interacts with OCT1 and OCT2 transcription factors and contributes to the transcriptional activity of octamer motifs. BOB-1 has been reported to be detectable in all B cell populations found in reactive lymphoid tissues. The strongest expression being found in germinal center B cells and plasma cells. The expression of BOB-1 in B cell tumors has been reported to be variable. Also available as a liquid concentrate, refer to page 98 Lymphoma: immunohistochemical staining with BOND ready-to-use BOB-1 (TG14) using BOND Polymer Refine Detection.
