Histone H3 (1-21) K9Ac-GGK(Biotin)

H3K9ac is an active-chromatin acetylation mark enriched near transcriptionally active promoters. This free-acid biotinylated form provides a defined ligand for acetyl-lysine reader and histone-binding studies.

• H3K9ac reader binding
• bromodomain research
• streptavidin pull-downs
• chromatin-state assays

This free-acid GGK(Biotin) form is distinct from the H3K9Ac-GGK(Biotin)-NH2 product already represented in the master.
