General description
Hannahan’s 肉汤 (SOB)是用于制备和转化感受态细胞（大肠杆菌）的微生物生长培养基。 酪蛋白酶解产物和酵母提取物为重组 大肠杆菌提供含氮化合物和生长因子。氯化钾和氯化钠可维持细胞的等渗环境。培养基中加入硫酸镁，作为 DNA 复制的必要成分。
Application
建议将Hanahan′s Broth用于大肠杆菌的重组菌株的培养。它适用于制备感受态 大肠杆菌，通常添加0.4％的葡萄糖。它还可用于制备 钩虫贪铜菌 H16 感受态细胞。它适用于 大肠杆菌 菌株的非选择性培养，用于克隆、生产DNA质粒和生产重组蛋白。
Features and Benefits
Hannahan′s Broth（SOB）粉末提供：
- 标准配方
- 液体形式的廉价替代品
Preparation Note
通过搅拌使28g粉末悬浮在1L水中。在121℃下高压灭菌15分钟。在加入添加物，例如抗生素（如果需要），之前请先冷却。
Other Notes
酪蛋白酶酶解产物和酵母抽提物提供了必要的氮化合物和生长因子。 氯化钾和氯化钠为细胞提供了等渗环境。 硫酸镁有助于DNA复制。
