AbFlex® Bcl6 antibody (rAb), sample

AbFlex antibodies are recombinant antibodies (rAbs) that have been generated using defined DNA sequences to produce highly specific, reproducible antibodies. Each AbFlex antibody contains a 6xHis Tag, a Biotinylation Tag for enzymatic biotin conjugation using the biotin ligase, BirA, and a sortase recognition motif (LPXTG) to attach a variety of labels directly to the antibody including fluorophores, enzymatic substrates (HRP, AP), peptides, drugs as well as solid supports. AbFlex Bcl6 antibody was expressed as full-length IgG with mouse immunoglobulin heavy and light chains (IgG2a isotype) in mammalian 293 cells. 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.
