Anti-acetyl-Histone H3 (Lys14) Antibody

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. Acetylation of histone H3 occurs at several different lysine positions in the histone tail and is performed by a family of enzymes known as Histone Acetyl Transferases (HATs). Acetylation of lysine14 is commonly seen in genes that are being actively transcribed into RNA.

Broad species-cross reactivity is expected.

Recognizes acetyl-histone H3 (Lys14), Mr ~17 kDa. An additional unknown protein was detected at Mr ~33 kDa.

Epitope: a.a. 9-18

Ovalbumin-conjugated, synthetic peptide (KSTGGAcKAPRK-C) corresponding to amino acids 9-18 of yeast histone H3 acetylated on lysine 14, with a C-terminal cysteine added for conjugation purposes.

Anti-acetyl-Histone H3 (Lys14) Antibody is a rabbit polyclonal antibody for detection of acetyl-Histone H3 (Lys14) also known as H3K14Ac, Histone H3 (acetyl K14) & has been validated in ChIP, WB, ChIP-seq, DB, Mplex.

Chromatin Immunoprecipitation (ChIP):
An independent laboratory has shown this antibody preferentially immunoprecipitates chromatin from wild type yeast and not from yeast strains containing a Lysine substitution to Alanine at residue 14.

Beadlyte Histone-Peptide Specificity Assay:
1:1000-1:5000 dilutions of a previous lot were incubated with histone H3 peptides containing various modifications conjugated to Luminex microspheres. No cross-reactivity with peptides containing acetyl-lysine 9 or acetyl-lysine 27 was detected.
