| WB | Western blot analysis of extracts from Hela (lane 1) and NIH3T3 (lane 2) and M-lymph (lane 3) using Acetyl-Histone H3 (Lys27) antibody. Proteins were transferred to a PVDF membrane and blocked with 5% nonfat powdered milk in PBST for 2 hour at room temperature. The primary antibody (1/1000) and Loading control antibody (GAPDH, 1/3000) was diluted with 5% nonfat powdered milk in PBST at 4°C overnight. Goat Anti-Rabbit IgG-HRP Secondary Antibody (1/8,000) was incubated for 45min at room temperature. |
| FC | Flow cytometric analysis of 1X10 6 HeLa cells labeling Acetyl-Histone H3 (Lys27) Antibody (HY-P80530, red). Cells were fixed with 4% paraformaldehyde and permeabilised with 90% methanol. Then stained with the primary antibody at 1/1000 dilution for an hour at 4℃. AF488-conjugated Goat Anti-Rabbit IgG H&L ( HY-P8002 ) was used as the secondary antibody at 1/1,000 dilution for 30 minutes at 4℃. Rabbit IgG Isotype Control (HY-P80879, blue) was used as the isotype control, cells without incubation with primary antibody were used as the unlabeled control (black). |

背景信息
功能: 乙酰化组蛋白 H3 是核小体的核心组分。核小体将 DNA 缠绕并压缩为染色质,限制了以 DNA 为模板的细胞机器对 DNA 的可及性。因此,组蛋白在转录调控、DNA 修复、DNA 复制和染色体稳定性中发挥核心作用。DNA 的可及性通过一系列复杂的组蛋白翻译后修饰 (也称为组蛋白密码) 以及核小体重塑来调控。 亚细胞定位: 细胞核;染色体 亚基: 核小体是由组蛋白八聚体组成,包含两个 H2A、两个 H2B、两个 H3 和两个 H4 分子,组装成一个 H3-H4 异源四聚体和两个 H2A-H2B 异源二聚体。该八聚体包裹约 147 bp 的 DNA。核小体与 TONSL、CHAF1A、CHAF1B、MCM2 和 DNAJC9 相互作用 (PubMed:33857403)。核小体还与 NASP 相互作用;NASP 是一种组蛋白伴侣,能够稳定并维持可溶性组蛋白 H3-H4 二聚体 (PubMed:22195965)。
