The Acetyl-Histone Antibody Sampler Kit provides a fast and economical means of evaluating the acetylation states of histones H2A, H2B, H3 and H4. The kit contains enough primary and secondary antibodies to perform four Western blot experiments.
Specificity / Sensitivity
Each acetyl-histone antibody recognizes only the indicated protein target modified at the indicated site. Each control histone antibody recognizes the corresponding histone regardless of its acetylation state.
Source / Purification
Polyclonal antibodies are produced by immunizing animals with synthetic acetylated peptides corresponding to residues surrounding Lys5 of histone H2A, Lys5 of histone H2B, Lys9 of histone H3, Lys8 of histone H4, with synthetic peptides corresponding to the amino-terminal sequences of human histone H2A, or the carboxy-terminal sequences of human histone H2B. Polyclonal Antibodies are purified by protein A and peptide affinity chromatography. Monoclonal antibodies are produced by immunizing animals with synthetic peptides corresponding to a synthetic peptide corresponding to the carboxy terminus of the human histone H3 protein or the amino-terminal sequences of human histone H4 protein. Acetyl-Histone H3 (Lys9) (C5B11) monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to the amino terminus of histone H3 in which Lys9 is acetylated.
Modulation of chromatin structure plays an important role in the regulation of transcription in eukaryotes. The nucleosome, made up of DNA wound around eight core histone proteins (two each of H2A, H2B, H3, and H4), is the primary building block of chromatin (1). The amino-terminal tails of core histones undergo various post-translational modifications, including acetylation, phosphorylation, methylation, and ubiquitination (2-5). These modifications occur in response to various stimuli and have a direct effect on the accessibility of chromatin to transcription factors and, therefore, gene expression (6). In most species, histone H2B is primarily acetylated at Lys5, 12, 15, and 20 (4,7). Histone H3 is primarily acetylated at Lys9, 14, 18, 23, 27, and 56. Acetylation of H3 at Lys9 appears to have a dominant role in histone deposition and chromatin assembly in some organisms (2,3). Phosphorylation at Ser10, Ser28, and Thr11 of histone H3 is tightly correlated with chromosome condensation during both mitosis and meiosis (8-10). Phosphorylation at Thr3 of histone H3 is highly conserved among many species and is catalyzed by the kinase haspin. Immunostaining with phospho-specific antibodies in mammalian cells reveals mitotic phosphorylation at Thr3 of H3 in prophase and its dephosphorylation during anaphase (11).
