The Histone Deacetylase (HDAC) Antibody Sampler Kit provides a fast and economical means to evaluate the endogenous levels of HDACs. The kit contains enough primary and secondary antibodies to perform four mini-blot experiments. Each antibody in the Histone Deacetylase (HDAC) Antibody Sampler Kit detects endogenous levels of its target and does not recognize other family members.
Source / Purification
Polyclonal antibodies are produced by immunizing animals with synthetic peptides corresponding to the carboxy terminus of human HDAC5 protein. Antibodies are purified by protein A and peptide affinity chromatography. Monoclonal antibodies are produced by immunizing animals with a recombinant protein specific to the carboxy terminus of human HDAC6, the amino terminus of human HDAC4 protein or with synthetic peptides to the carboxy-terminal residues of human HDAC1 and HDAC2 proteins. HDAC3 (7G6C5) monoclonal antibody is produced by immunizing animals with recombinant human HDAC3 protein.

Background
Acetylation of the histone tail causes chromatin to adopt an "open" conformation, allowing increased accessibility of transcription factors to DNA. The identification of histone acetyltransferases (HATs) and their large multiprotein complexes has yielded important insights into how these enzymes regulate transcription (1,2). HAT complexes interact with sequence-specific activator proteins to target specific genes. In addition to histones, HATs can acetylate nonhistone proteins, suggesting multiple roles for these enzymes (3). In contrast, histone deacetylation promotes a "closed" chromatin conformation and typically leads to repression of gene activity (4). Mammalian histone deacetylases can be divided into three classes on the basis of their similarity to various yeast deacetylases (5). Class I proteins (HDACs 1, 2, 3, and 8) are related to the yeast Rpd3-like proteins, those in class II (HDACs 4, 5, 6, 7, 9, and 10) are related to yeast Hda1-like proteins, and class III proteins are related to the yeast protein Sir2. Inhibitors of HDAC activity are now being explored as potential therapeutic cancer agents (6,7).
