The method of plasmid is the method of solution 123.
For DNA, please refer to the method of extracting DNA from animals and plants.
For a faster method, we can refer to our method of colony PCR, which uses a small number of bacteria as a template.
Then the PCR reaction solution is added, and the bacterial cell wall will be lysed off during the PCR high-temperature pre-denaturation, and both DNA and plasmid will be released into the solution as templates to participate in amplification.
If you have a 96-well deep plate (1-2ml) and a platoon gun, it is best to save time and trouble. Toothpicks or pipette heads pick a little bit of bacteria (as long as they are stained with colonies, they do not require large pieces, large pieces are not good), add 500ul culture medium to each well of 96 wells, pick 96 pieces, and then take them to shake the bacteria, culture for 3-5 hours, and the bacteria solution can be directly used as a template for PCR.
As long as the primers are easy to use, they can basically be expanded. We identify positive clones all doing this, you can refer to it.
