Mach1 T1R 是可快速生长的化学感受态菌株 (图 1)。在平板上接种转化细胞后八小时内,菌落即清晰可见 (仅限氨苄青霉素筛选)。Mach1 T1R 感受态细胞由于 tonA (fhuA) 基因型缺失而对噬菌体具有抗性,被命名为 Mach1 T1R。噬菌体抗性可保护细胞免受 T1、T5 和 φ80噬菌体的裂解。
图 1.与标准克隆相比, Mach1 T1 RE. coli 具有更快的生长率。将 pUC19 转化 Mach1 T1R 、XL10-Gold、TOP10、XL1-Blue 和 DH5α E.coli ,并过夜培养。在 500 mL 培养瓶中,每种培养物按 1:50 的比例接种于 50 mL 含氨苄青霉素抗性的培养基中。5.5 小时内每 30 分钟测量一次生长情况。Mach1 T1R 细胞达到所需光学密度 (如用于小量制备分析) 的速度显著快于其他测试菌株。
Mach1 感受态细胞的优势
- 双倍的快速生长可实现在同一天进行涂板和菌落挑选
- 在生长 4 小时后即可进行小量制备 (图 2)
- Mach1 T1R 细胞可以方便的单次使用 One Shot 形式和高通量 MultiShot 形式提供
