synthetic peptide (C-SGEKTDTKGTKSEQLSNP) corresponding to the C-terminus region of histone deacetylase 2 of human origin (amino acids residues 471-488 with N-ternimal added cysteine) conjugated to maleimide-activated KLH. This sequence is highly conserved in mouse and chicken (2 amino acids and 1 amino acid substitutions, respectively).

General description

Histone acetylation is a dynamic process whose levels are determined by the net activities of HATs and the competing enzymes histone deacetylases (HDACs). Both activities are associated with the nuclear matrix. Six or seven different mammalian HDACs have been described. HDAC1, HDAC2 and HDAC3 are similar to yeast Rpd3 protein, while HDAC4, HDAC5 and HDAC6 are similar to yeast Hda1 protein. Histone deacetylases activities were often, but not always, associated with transcriptional repression and nucleosomal condensations. HDAC1, HDAC2 and several other HDACs are the catalytic subunits of different multiprotein regulatory complexes.

Physical form

Solution in 0.01 M phosphate bufffered saline, pH 7.4, containing 15 mM sodium azide.


Anti-Histone Deacetylase 2 specifically recognizes histone deacetylase 2 by immunoblotting and immunoprecipitation (55 kDa). An additional band of lower molecular weight may be detected in some cell line extracts by immunoblotting. Staining of HDAC2 by immunoblotting is specifically inhibited with the immunizing peptide. The product is also useful for the detection of HDAC2 by immunohistochemistry. The epitope(s) recognized by the antibody is resistant to routine formalin-fixation and paraffin embedding. The antibody reacts with HDAC2 of human, rat and mouse origin.
