If you are going to cut out the gel bands yourself from a gel, please follow carefully the following instructions:

  • ONLY cut gels on a clean glass plate (never use overhead projector foils)
  • Wear gloves at all times
  • Use a NEW clean scalpel blade for precise cutting
  • PRECISELY cut out ONLY the band - any excess gel will lead to background noise
  • Chop the gel band into approx 1 mm squares
  • Place the gel cubes in a clean eppendorf tube (500 µL) and add enough water just to cover
  • Check the lid is shut before placing in an envelope to send.
  • Please DO NOT use parafilm around the lids
