Rationale: run pcr reactions on a gel to see if phage DNA was found and replicated in the soil sample

Process:

  1. 0.8 g of agarose were dissolved in 40 mL TBE (Tris/Borate/EDTA) buffer
    1. a microwave was used to heat the mixture in order to dissolve the agarose
  2. Once the mixture cooled, the TA added Ethidium Bromide
  3. The mixture was poured into a gel tray and left to solidify
  4. the solidified gel was then placed in a gel box and submerged in TBE buffer
  5. the pcr reactions and ladder were pipetted into the wells according to the following table
    1. lane sample amount
      1 RSM & SJ PM1 10 µL
      2 RSM & SJ PM2 10 µL
      3 RSM & SJ PM3 10 µL
      4 Ladder 5 µL
      5 shared 10 µL
      6 shared 10 µL
      7 shared 10 µL
  6. the electrodes were connected to the gel box and the gel was run for about 30 minutes
  7. Once the yellow marks had moved about 3/4 of way down the gel, the gel was taken out to be photographed with the gel imaging machine

 

Results:

gel run on 10/22/2018 showing only bands from the ladder

Next Steps:

The results showed no sign of phage DNA in our soil samples so my group decided on collecting a new sample and enriching yet again
