Gel-Electrophoresis protocol
  • Preparation of the Gel (50mL)
    • Mix 0.5 grams of agarose with 50mL 0.5% TAE solution
    • Heat the Erlenmeyer (conical flask) in a microwave until the liquid becomes totally transparent.
    • Let it rest until you can take the Erlenmeyer in your hand without pain for 10 seconds.
    • Add 5uL of SYBR® Safe (10000X) and mix gently until the solution homogenizes.
    • Pour the liquid in a gel mold with the desired number of wells and wait 20-30 min (or until the gel is solidified).
    • Put the gel inside the electrophoresis machine and pour TAE 0.5% until the gel is totally submerged.
  • Preparation of the samples
    • Mix 5uL of each sample with 1uL of 6X loading dye in microcentrifuge tubes (or any hydrophobic surface like parafilm)
    • Pipette 5-6uL of each sample inside a different well.
    • Pipette 5uL of the appropriate ladder in one of the wells (Some ladders have a dye in it, but some don't, so one has to add gel loading dye to these ones)
    • Close the machine and launch the migration with the desired voltage
    • After the desired migration time turn off the machine, remove the lid and put the gel inside the gel visualizer.
