Monoclonal Antibody for studying BCL6. Validated for Western Blotting. Highly specific and rigorously validated in-house, BCL6 (D4I2V) Rabbit Monoclonal Antibody (Biotinylated) (CST #71464) is ready to ship. Product Usage Information Western Blotting: 1:1000 Storage Supplied in 140 mM NaCl, 3 mM KCI, 10 mM sodium phosphate (pH 7.4) dibasic, 2 mM potassium phosphate monobasic, 2 mg/mL BSA, and 50% glycerol. Store at -20°C. Do not aliquot the antibody. Protocol Available protocols: Western Blotting Specificity / Sensitivity BCL6 (D4I2V) Rabbit Monoclonal Antibody (Biotinylated) recognizes endogenous levels of total BCL6 protein. This antibody is predicted to detect both human BCL6 isoform 1 and isoform 2. Species Reactivity: Human Source / Purification Monoclonal antibody is produced by immunizing animals with a recombinant protein fragment spanning residues Asp210 through Thr409 of human BCL6 protein. Background Chromosomal translocations result in misregulation of the proto-oncogene in patients with B cell-derived non-Hodgkin's lymphoma (1). The gene is selectively expressed in mature B cells and encodes a nuclear phosphoprotein that belongs to the BTB/POZ zinc finger family of transcription factors (2,3). BCL6 protein can bind to target DNA sequences of Stat6 and, analogous to Stat6, modulate the expression of interleukin-4-induced genes (4). Furthermore, BCL6 restrains p53-dependent senescence, making BCL6-active tumors functionally p53-negative (5). The mitogen-activated protein kinases, Erk1 and Erk2, but not JNK, phosphorylate BCL6 at multiple sites. Phosphorylation of BCL6 at Ser333 and Ser343 results in degradation of BCL6 by the ubiquitin/proteasome pathway in B cells (6,7). In addition, BCL6 is acetylated and its transcriptional repressor function is inhibited by the transcriptional co-activator p300 (8).
