Application Notes
Applications Validated by Active Motif:
WB: 0.5 – 2 µg/ml
Note: For optimal results, we recommend a High Salt / Sonication Protocol when preparing nuclear extracts for Western blot.
Immunogen
This antibody was raised against a peptide containing mono-methyl lysine 4 of Histone H3.
Buffer
140 mM Hepes, pH 7.5, 70 mM NaCl, 32 mM NaOAc, 0.035% sodium azide, and 30% glycerol. Sodium azide is highly toxic.
AbFlex® Histone H3K4me1 antibody (rAb) tested by Western blot.
20 µg of HeLa cell nuclear extract was run on SDS-PAGE and probed with AbFlex Histone H3K4me1 antibody at 0.5 µg/ml. Note: For optimal results, we recommend a High Salt / Sonication Protocol when preparing nuclear extracts for detection of Histone H3K4me1.
AbFlex® Histone H3K4me1 antibody (rAb) specificity tested by peptide array analysis.
Peptide array analysis was used to confirm the specificity of this antibody for its intended modification. Histone H3 trimethyl Lys27 antibody was applied at 0.2 µg/ml to Active Motif's MODified™ Histone Peptide Array (Catalog No. 13001). The arrays were scanned with ArrayAnalysis Software 7 and the results plotted. Recognition of the H3K4me1 peptides by the antibody is blocked by phosphorylation at Thr3.
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 H3K4me1 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 nucleosome is the smallest subunit of chromatin and consists of 147 base pairs of DNA wrapped around an octamer of core histone proteins (two each of Histone H2A, Histone H2B, Histone H3 and Histone H4). Histone H1 is a linker histone, present at the interface between the nucleosome core and DNA entry/exit points. Histone H1 is responsible for establishing higher-order chromatin structure. Chromatin is 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.
