Description

General description

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. Histone proteins are highly post-translationally modified, and Histone H3 is the most extensively modified of the five histones. The term "Histone H3" alone is purposely ambiguous in that it does not distinguish between sequence variants or modification state. Histone H3 is an important protein in the emerging field of epigenetics, where its sequence variants and variable modification states are thought to play a role in the dynamic and long term regulation of genes.

Other Notes

Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.

Specificity

Broad species cross-reactivity is expected, based on sequence homology.

This antibody recognizes Histone H3 that is unmodified at Thr3 and Lys4 but does not recognize phosphorylated Thr3 nor acetylated or methylated Lys4. The antibody binding specificity allows modifications of Lys9, Ser10, and/or Lys141.

Immunogen

Epitope: N-terminus (unmodified)

Synthetic peptide corresponding to amino acids 1-12 of human Histone H3, conjugated to KLH.
