7. Plate 100µL of the medium and spread well.
8. Incubate the plate on 37℃.

Electrophoresis

Method
1. Make a gel for electrophoresis
2.Add Agarose to 30ml or 15ml of 1xTAE buffer in Erlenmeyer flask per 1 gel plate. The concentration of gel is 1% for over 1kbp of DNA and use 2% to under 1kbp.
3.Wrap the top of Erlenmeyer Flask not to completely seal up.
4.Heat it by microwaves until the solution gets transparent.
5.Pour it into a maker and set a comb before it get hard.
6.After the gel get hard , remove the comb carefully not to break well.
7.Place maker into tank for electrophoresis and fill 1xTAE up to over the level of gel .
8. Add 2µl of 6xLoading buffer into 10µl of DNA solution and vortex it.
9. Apply 12µl of sample and 6µl of ladder solution in each well.
10. Electrophoresis at 100V for 20-30 minutes.
11. The marker band reaches 80% of the gel, stop electrophoresis and salvage the gel.
12. Put it to the ethidium bromide solution for 15 min for staining.
13. Check the band under blue light.

Colony PCR

Method
1.
2. Dispense it to each PCR tube for 10µl on ice.
3. Pick up single colony on plate and dip to the tube.
4. Set to Thermal cycler.
5.Check the length of DNA by Electrophoresis.

Miniprep

Material
Wizard® Plus SV Minipreps DNA Purification System (promega)
Method
1. Pour 3ml of LB liquid to test tube.
2. Pick up a single colony and put it into the tube.
3. Incubate it at 37℃ for 8 hours with the tube shaking.
4. Transfer 1.5ml of culture fluid to 1.5ml tube.
5. Centrifuge at 15000rpm for 1minutes.
6. Throw away the supernatant and add the other 1.0ml.
7. The same as 5 and 6 and be only precipitation.
8. Add 250µl of Cell-Resuspension Sol and Vortex it until precipitation dissolved.
9. Add 250µl of Cell-Lysis Sol and invert it not to make bubble.
10. Add 10µl of Alkaline Protease and invert it not to make bubble
11. Leave it for a few minutes at room temperature.
12. Add 350ml of Neutralization Sol and invert it not to make bubble.
13. Centrifuge at 15000rpm 10min.
14. Set a collection tube on column and apply sup to it.
15. Centrifuge at15000rpm for 1min.
16. Add 750µl of Column Wash Sol and Centrifuge for 1min at 15000rpm.
17. Add 250µl of Column Wash Sol and Centrifuge for 1min at 15000rpm.
