Product Data Sheet

Transformation of plasmid DNA to competent E. Coli cells

1. Thaw competent cells on ice. 20–200µL per tube
2. Add max. 1-3µL of plasmid
3. Mix very gently!
4. Incubate the tubes on ice for 30 min
5. Heat shock the cells for 45 sec to 2 min at 42°C
6. Place the tubes immediately on ice for at least 2 min
7. Add 800µL of SOC medium to each tube
8. Incubate for 1 hour at 37°C and shake vigorously
9. Spin down briefly and remove most supernatants
10. Resuspend cell pellet with the rest SOC medium in the tube by pipetting
11. Plate out the suspension on a LB agar plate containing the appropriate antibiotic. Incubate the plates overnight at 37°C

载体描述：

Takara的pCold TF载体是一种融合表达可溶性的标签"触发因子（Trigger Factor,TF）伴侣"的冷休克载体。"触发因子"（48KD）是原核核糖体相关的分子伴侣蛋白（48 kDa），有利于新表达的多肽的共翻译折叠。正因为它来源于大肠杆菌，保证了触发因子能够在大肠杆菌表达系统中高表达。 pCold TF载体由CSPA启动子及其下游的序列组成，其下游序列主要包括包括5非翻译区（5非编码区），翻译增强元件（TUNEology 波长可调检测卡盒-->
