AbFlex® Mi-2 beta (CHD4) antibody (rAb)

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 Mi-2 beta (CHD4) antibody was expressed as full-length IgG with mouse immunoglobulin heavy and light chains (IgG2a isotype) in mammalian 293 cells. Mi-2b (Mi-2 beta, CHD4, chromodomain helicase DNA-binding protein 4) represents the major Mi-2 isoform present in the complex Mi-2/NuRD. This complex is a multi-subunit protein complex containing both histone deacetylase and nucleosome-dependent ATPase subunits. Current models predict that this complex functions primarily in transcriptional repression. In addition to the ATPase domain, Mi-2 beta contains a chromodomain and two PHD domains. Mi-2 beta interacts with BRG-1, a component of the SWI/SNF complex, and the RET finger protein (RFP).
