  1. Preparation of the LB agar
    We used 37 g of nutrient agar for 400 mL of distilled water
  2. Extraction of genome from S.mutans
    1. First, culture S.mutans in 5 mL liquid BHI + bacitracin
    2. Centrifuge for 15 min at 4000 rpm
    3. Then dissolve the pellet in 500 microliters of Lysis Buffer
      How to prepare Lysis Buffer (1 mL):
      Lysis Buffer contains EDTA, Tween 80%, tris HCl,125 microliters of 8 M EDTA,5 µl of Tween 80, Tris HCl 1M 50 µl, Proteinase K (200 µg/mL). 0.0002 grams of powder Proteinase K were put into 1 mL of Lysis Buffer. The balance could not read 0.0002 g of proteinase K, so 0.02 g of proteinase K were taken.
  3. Incubation for 2 hours at 55°C. Heat at 90°C for 5 minutes.
  4. Then add equal volume of cold isopropyl alcohol.
  5. Incubate in freezer for 20 minutes.
  6. Centrifuge at the maximum speed for 30 min. Remove the supernatant.
  7. Add enough amount of ethanol to the pellet in order to wash
  8. Then add 50 µl of TE buffer
  9. Add 0.5 µl of the RNAase
  10. Incubate at 37°C for 1 hour
  11. Inactivate at 60°C for 10 min
  12. Run it in an agarose gel

Another is 2000 base pair. However, if Pveg+ FixJ ligation have worked there would be also uncut plasmid after digestion of size 4500. So, it was decided to make single digest with EcorI in order to check if there would be a liniarized plasmid of 4500 base pair size. Activity №2.
