一般說明
Lennox LB是一个被高度引用的用于 大肠杆菌培养的微生物生长培养基。这种富含营养的微生物肉汤含有肽、氨基酸和低盐配方的碳水化合物。
應用
Luria肉汤被用于大肠杆菌（Escherichia coli）的维持和繁殖。 大肠杆菌在Luria肉汤中生长得更快，因为胰蛋白胨和酵母为其提供了必需的生长因子，从而无需大肠杆菌自身合成。由于含有NaCl成分，Luria肉汤还含有转运和渗透平衡所必需的电解质。
在三鞭毛虫细胞提取物的分级研究中，它被用于梨形四膜虫胞级分的重悬。
在三鞭毛虫细胞提取物的分级研究中，它被用于梨形四膜虫胞级分的重悬。
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。 也适用于添加适当抗生素时的选择性培养，包括需要低盐条件的抗生素，如吉欧霉素®。
特點和優勢
Lennox LB粉末可提供：
- 便捷式小包装，无需称重步骤
- 使用大包装可轻松放大规模
- 一种预算较低的液体替代品
- 标准配方
