Histone H3 is one of the five main histone proteins involved in the structure of chromatin in eukaryotic cells. Featuring a main globular domain and a long N-terminal tail, H3 is involved with the structure of the nucleosomes of the ′beads on a string′ structure. The N-terminal tail of histone H3 protrudes from the globular nucleosome core and can undergo several different types of epigenetic modifications that influence cellular processes. These modifications include the covalent attachment of methyl or acetyl groups to lysine and arginine amino acids and the phosphorylation of serine or threonine.
Broad species-cross reactivity is expected.
Recognizes acetyl-histone H3 (Lys9), Mr 17 kDa. An additional unknown protein was detected at Mr 23 kDa.
Epitope: a.a. 4-14
Ovalbumin-conjugated, synthetic peptide (KQTARAcKSTGGK-C) corresponding to amino acids 4-14 of yeast histone H3 acetylated on lysine 9, with a C-terminal cysteine added for conjugation purposes.
Anti-acetyl-Histone H3 (Lys9) Antibody is a Rabbit Polyclonal Antibody for detection of acetyl-Histone H3 (Lys9) also known as H3K9Ac, Histone H3 (acetyl K9) and has been published and validated in ChIP, WB, Mplex.
Chromatin Immunoprecipitation (ChIP):
An independent laboratory has shown this antibody preferentially immunoprecipitates chromatin from wild type yeast and not from a yeast strain containing a Lysine substitution to Alanine at residue 9.
Beadlyte Histone-Peptide Specificity Assay:
A 1:1000-1:5000 dilution of this lot was incubated with histone H3 peptides containing various modifications conjugated to Luminex microspheres. No cross-reactivity with peptides containing acetyl-lysine 14 or acetyl-lysine 27 was observed.
