Protocols


Electrophoresis

(estimated time: 2 hours)

  • Prepare agarose gel in 1x TBE buffer
  • Add ethidium bromide (using gloves and face mask for your safety):
    • 1 µl in the small size agarose gel (70 ml)
    • 2 µl in the middle size agarose gel (150 ml)
    • 4 µl in the big size agarose gel (250 ml)
  • Cast the gel, insert the well-forming comb and let it polymerize
  • Add the loading buffer to each sample
  • Load the samples and 8 µl of marker
  • Set to 70-100 volts and electrophorese for the required amount of time
  • Use UV-light to look at the bands
  • Take a picture of the gel, if needed (not when bands have to be cut!!!)
