Gel Electrophoresis 10/22/2018
Rationale: run pcr reactions on a gel to see if phage DNA was found and replicated in the soil sample
Process:
- 0.8 g of agarose were dissolved in 40 mL TBE (Tris/Borate/EDTA) buffer
- a microwave was used to heat the mixture in order to dissolve the agarose
- Once the mixture cooled, the TA added Ethidium Bromide
- The mixture was poured into a gel tray and left to solidify
- the solidified gel was then placed in a gel box and submerged in TBE buffer
- the pcr reactions and ladder were pipetted into the wells according to the following table
-
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
-
- the electrodes were connected to the gel box and the gel was run for about 30 minutes
- 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:
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
