pETBlue-2 plasmid

Subculture procedure	1. Dissolution: Upon receiving the plasmid Freeze dried pellet, add 20μl sterile water to the bottom of the tube to dissolve the plasmid. Incubate at Room temperature for 1 minute. 2. Mixing (Plasmid Adsorption): Add 200μl competent cells + 5–10μl plasmid DNA, mix thoroughly, and incubate on ice for 30 minutes. 3. Heat shock transformation: Incubate at 42°C for 90 seconds; 4. Cooling shock: Ice-bathe for 2 minutes; 5. Repair culture: Add 800μl LB liquid medium to each tube. Incubate at 37°C for 1 hour at 150 rpm; 6. Screening culture: Spread an appropriate volume (100 µl) of revived cells onto LB plates with the corresponding antibiotic. Incubate plates upright for 30 min (ensure agar surface is completely dry), then invert and incubate for 12–16 h until colonies appear. 7. Extraction: Transfer a single colony to LB liquid medium with the corresponding antibiotic, shake-incubate for 12-16 hours, and extract the plasmid as required for the experiment.
