This Bcl6 antibody was raised against a full-length protein corresponding to human Bcl6.


Purified IgG in PBS with 30% glycerol and 0.035% sodium azide. Sodium azide is highly toxic.



Bcl6 (B-cell lymphoma 6 protein, Bcl5, LAZ3, ZBTB27, ZNF51) is sequence-specific transcriptional repressor that is required for the formation of lymph node germinal centers (GC). Bcl6 is a member of the BTB-POZ family of transcriptional regulators and contains six Kruppel-type zinc fingers. The POZ domain in the amino terminus of Bcl6 is involved in the recruitment of corepressor proteins including NCoR, BCoR, SMRT, Mi-2/NURD and several HDACs. Bcl6 promotes proliferative expansion of B-cells in the germinal center through repression of genes regulating cell cycle and differentiation. Bcl6 also suppresses the DNA damage response, to prevent class-switch recombination being repaired. Unregulated expression of Bcl6 is involved in the development of many B-cell lymphomas.


Some products may be shipped at room temperature. This will not affect their stability or performance. Upon receipt, unconjugated antibodies may be stored at -20°C for up to 2 years. Fluorophore- & enzyme-conjugated antibodies should be stored at 4°C. Fluorophore-conjugated antibodies should be protected from light. Keep reagents on ice when not in storage; to avoid repeated freeze/thaw cycles, we recommend aliquoting items that will be stored frozen into single-use fractions prior to freezing.


This product is guaranteed for 6 months from date of receipt.
