Clonality - X Chromosome Inactivation Assay

(1:1:1, v:v:v) (Gibco) 3 M Na Acetate, pH 5.2 (Life Technologies) Isopropanol Glycogen, 10 mg/ml (GenHunter) 70% ethanol Buffer 1 (50 mM Tris-HCl, pH 8.0, 10 mM MgCl2, 50 mM NaCl) Hha I restriction enzyme (Life Technologies) REact 2 Buffer

A protocol for cleaning and reusing the large 25 x 25 cm plates

). For our sink, I fill the sink about 3/4 full (approximately 50 litters) and add 500 to 1000 ml Clorox. (500 ml gives a final concentration of about 1% bleach). I let the plates soak in the dilute bleach solution for approximately 1/2 hour

交联染色质免疫共沉淀（X-ChIP）实验设计

。加入甘氨酸可以消除甲醛使交联反应终止。1.1.准备两个长满细胞的150cm2的细胞培养皿（1*107-5*107 个细胞/皿）。将甲醛直接滴入PBS洗过的细胞培养皿中，使其终浓度为0.75%，然后在室温缓慢旋转10分钟，使蛋白和DNA发生交联。1.2 加入甘氨酸使其终浓度为125mM,在室温晃动孵育5分钟。1.3 使用10ml预冷PBS清洗细胞2次1.4 使用细胞刮将细胞收获放入 5ml 预冷PBS中，并转入50ml的管子。1.5.在皿里加入3mlPBS，将剩余的细胞转移到50ml管子里1000g
