| Background | The Stat1 transcription factor is activated in response to a large number of ligands (1) and is essential for responsiveness to IFN-α and IFN-γ (2,3). Phosphorylation of Stat1 at Tyr701 induces Stat1 dimerization, nuclear translocation, and DNA binding (4). Stat1 protein exists as a pair of isoforms, Stat1α (91 kDa) and the splice variant Stat1β (84 kDa). In most cells, both isoforms are activated by IFN-α, but only Stat1α is activated by IFN-γ. The inappropriate activation of Stat1 occurs in many tumors (5). In addition to tyrosine phosphorylation, Stat1 is also phosphorylated at Ser727 through a p38 mitogen-activated protein kinase (MAPK)-dependent pathway in response to IFN-α and other cellular stresses (6). Serine phosphorylation may be required for the maximal induction of Stat1-mediated gene activation. |

说明书推荐的反应体系进行 CUT&Tag 实验；其中，pG-Tn5 转座子使用的终浓度为 0.04μM ，一抗为 H3K27me3（CST，#9733），二抗为 Goat anti Rabbit（Bioworld，#BS13271）。 A、文库峰型检测 使用 Agilent 2100 Bioanalyzer 进行文库分布检测。 图 2. 使用 TD901 构建 100 cells CUT&Tag 文库峰型图 图 3. 使用 TD901 构建 10,000 cells CUT&Tag
h）即可。2. 修复大法——不仅仅是「煮一煮」微波炉修复：简单易行效果好，CST 推荐使用微波炉完成修复。合适的修复液：根据抗体说明书使用合适的修复液。用柠檬酸修复后，切片需浸泡在修复液中，自然冷却；而用 EDTA 修复后，切片可直接从修复缸中取出，直接进行下一步。注：使用不同的修复方式和不同生产商的抗体检测人肺癌组织中 EGFR 的表达。第一排为 CST 的 EGF Receptor (D38B1) XP® Rabbit mAb（#4267），EDTA 的修复方式明显优于柠檬酸盐及胃蛋白
