Changes in chromatin structure play a large role in the regulation of transcription in eukaryotes (1). The nucleosome is the primary building block of chromatin, and is made up of four core histone proteins (H2A, H2B, H3 and H4) (2). Acetylation of core histones regulates gene expression (2). Histone H3 is primarily acetylated at lysines 9, 14, 18, and 23 (3,4). Acetylation at lysine 9 appears to have a dominant role in histone deposition and chromatin assembly in some organisms (3,4).

|A. Western blot analysis on C6 cell lysate using anti-Histone H3 Acetyl (K18) RabMAb (cat. #1766-1), 1:50,000 dilution. Cells were (1) untreated or (2) treated with TSA.||B. Immunohistochemical staining of paraffin-embedded human breast carcinoma using anti--Histone H3 Acetyl (K18) RabMAb (cat. # 1766-1).|
A synthetic acetylated peptide corresponding to residues surrounding Lys18 of Histone H3 was used as immunogen. The antibody only detects Histone H3 acetylated on Lysine 18.
