| Molecular Weight (kDa) | 17 |
| Source/Isotype | Rabbit |
| Application/Dilution | {Western Blotting: 1:1000, Immunoprecipitation: 1:25, Chromatin IP: 1:25} |
| Storage | Supplied in 10 mm sodium HEPES (pH 7.5), 150 mm NaCl, 100 µg/mL BSA and 50% glycerol. Store at –20°C. Do not aliquot the antibody. |
| Specificity/Sensitivity | Acetyl-Histone H3 (Lys27) Antibody detects endogenous levels of histone H3 when acetylated on Lys27. This antibody shows weak cross-reactivity with histone H3 acetylated on Lys9. This antibody does not cross-react with Histone H3 acetylated on lysines 14, 18 and 56. |
| Species Reactivity | Human, Mouse, Rat, Monkey |
| Source/Purification | Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to the amino terminus of histone H3 in which Lys27 is acetylated. Antibodies are purified by protein A and peptide affinity chromatography. |
| Background | 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 posttranslational 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). |
