Application Notes
Applications Validated by Active Motif:
ICC/IF: 1 - 2 µg/ml
WB*: 0.1 - 1 µg/ml
Bead-based ELISA: 0.5 - 10 µg/ml
*Note: many chromatin-bound proteins are not soluble in a low salt nuclear extract and fractionate to the pellet. Therefore, we recommend a High Salt / Sonication Protocol when preparing nuclear extracts for Western Blot.
Immunogen
This antibody was raised against a synthetic branched peptide corresponding to amino acids surrounding Lys9 of human Histone H3.
Buffer
Purified IgG in 140 mM Hepes, pH 7.5, 70 mM NaCl, 32 mM NaOAc, 30% glycerol and 0.035% sodium azide. Sodium azide is highly toxic.

Background
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® Histone H3K9me0 antibody was expressed as full-length IgG with mouse immunoglobulin heavy and light chains (IgG2a isotype) in mammalian 293 cells.
Histone H3 is one of the core components of the nucleosome, the basic building block of chromatin. Histones are subject to a variety of chemical modifications, including post-translational modifications of the histone proteins and the methylation of cytosine residues in the DNA. Reported histone modifications include acetylation, methylation, phosphorylation, ubiquitylation, glycosylation, ADP-ribosylation, carbonylation and SUMOylation; these modifications play a major role in regulating gene expression.
Methylation of lysines occur as four states: unmethylated (me0), monomethyl (me1), dimethyl (me2) and trimethyl (me3). The me0 state of lysine is recognized as biologically relevant and a number of proteins containing PhD fingers, ADD and WD40 domains are known to associate with unmodified lysines.
