Anti-Histone H3.3 Antibody, K27M mutant (C15-1317-151)

General description

Histone H3.3 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, H3.3 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. Histone variant H3.3 is typically enriched in active chromatin.

Specificity

This antibody recognizes Histone H3.3 with K27M mutation.

Immunogen

Epitope: Histsone H3 sequence surrounding K27M mutation

KLH-conjugated linear peptide corresponding to sequence near the N-terminus of human Histone H3.3 with K27M mutation.

Application

Anti-Histone H3.3 Antibody, K27M mutant, is validated for use in western blotting (WB) & Chromatin immunoprecipitation (ChIP).
