Rabbit anti Trimethyl-Histone H3 (Lys 4)

Product Synonym Names
Rabbit anti-Trimethyl-Histone H3 (K4); Histone H3 trimethylated at Lys4 (H3-K4me3); H3K4[Me3].
Research Use Only
For Research Use Only. Not for use in diagnostic procedures.
Species Reactivity
Human, Mouse, Rat, Chicken, Bovine
This antibody only recognizes ~ 17 kDa of Trimethylated Histone H3 at K4. It does not cross react to nonmethylated H3 or mono-, di-methylated Histone H3.
The Rabbit IgG is purified by Site-modification specific Affinity Chromatography.
This affinity purified antibody is supplied in sterile Phosphatebuffered saline (pH7.2) containing antibody stabilizer
Antigen Preparation
A synthetic peptide containing RT[Me3-K]QT in which Me3-K corresponds to trimethyl lysine 4 of human histone H3.
Positive Control
3T3 Nuclear Extract
Cellular Location
Preparation and Storage
The antibodies are stable for 12 months from date of receipt when stored at -20 degree C to -70 degree C. The antibodies can be stored at 2 degree C-8 degree C for three month without detectable loss of activity. Avoid repeated freezing-thawing cycles.
Other Notes
Small volumes of anti-Trimethyl-Histone H3 (Lys4) antibody vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
Related Product Information for
anti-Trimethyl-Histone H3 (Lys4) antibody
Histones are basic nuclear proteins that together with DNA make up the nucleosome structure in eukaryotes. Nucleosomes consist of approximately 146 bp of DNA wrapped around a histone octamer composed of pairs of each of the four core histones (H2A, H2B, H3, and H4). The methylation of specific residues in the histone tails is a central modification for regulating epigenetic transitions in chromatin. Whereas methylation of histone H3 on lysine 4, 36, and 79 has been linked with gene activation, methylation of H3 on lysines 9, 27 and histone H4 on lysine 20 is associated with heterochromatin and some repressed genes with euchromatin. Modified lysine residues can exist in a mono-, di-, or tri methylated state, while the arginine residues can be mono- or di-methylated. Histone H3 Lys4 trimethylation (H3-K4me3) is a conserved mark of actively transcribed chromatin. This antibody is specific for histone H3 tri-methylated at K4. The sequence is found in all mammals and a wide range of species, including D. melanogaster, Arabidopsis, Chicken and Xenopus. The antibody will react with any of the above species where the trimethylation modification is present.
