  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 the S.mutans in 5 mL liquid BHI + bacitracin
    2. Centrifuge at 15 min for 4000 rpm
    3. Then dissolve the pellet in 500 microliter of lysis buffer
      How to prepare Lysis Buffer (1 mL):
      Lysis Buffer contains the EDTA, Tween 80%, tris HCl,125 microliter of 8M EDTA,5 µl of of Tween 80, Tris HCl 1M 50 µl, Proteinase K (we need 200 µg/mL). We took 0.0002 grams of powder Proteinase K for 1 mL of lysis The balance could not read 0.0002 grams of Proteinase K, so 0.02 of proteinase K was taken.
  3. Incubation for the 2 hours at 55°C. Then there is a need to heat at the 90°C for 5 minutes.
  4. Then add equal amount of cold isopropanol.
  5. There is a need to incubate in freezer for the 20 minutes.
  6. Centrifuge for the maximum speed for the 30 min. Remove 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 agarose gel

Checking of the Ligation of the Pveg+FixJ mini prep product by making sequential digest with SpeI (Sib enzyme) and EcoRI (fermentas) Results: There are two bands. One is the 2500 bp. 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.

The results shows that there is no linearized plasmid with the 4500 base pair after ligation. So ligation did not work. Activity №3.
