| Specificity / Sensitivity | Acetyl-Histone H2A (Lys5) Antibody detects endogenous levels of histone H2A only when acetylated at lysine 5. This antibody does not cross-react with other acetylated histones. |
| Source / Purification | Polyclonal antibodies are produced by immunizing animals with a synthetic acetylated peptide corresponding to residues surrounding Lys5 of human histone H2A. 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 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).

文献和实验组蛋白是和染色体相联的最主要的蛋白质。它的作用是和染色体中的 DNA 的负电荷结合。组蛋白是比较小的碱性蛋白;在细胞正常 pH 值时,组蛋白带有正电荷,这样它们就可以和 DNA 结合,这个正电荷主要存在于碱性氨基酸 Lys 和 Arg 的 -NH3 上。其实,组蛋白约含 25% 的 Arg 和 Lys 。比其他蛋白的 Arg , Lys 的含量都多。和真核 DNA 结合的有 5 种类型的组蛋白: H1 , H2A , H2B , H3
