Method including controls

Add to a sterile 1.7ml Eppendorf

  1. roughly equal quantity of DNA fragments to be ligated together (usually 5ul of both vector and insert if gel-purified)
  2. 2ul of 10X buffer or 10ul of 2X buffer
  3. 1ul of T4 DNA ligase
  4. milliQ water to make up to 20ul

Incubate Overnight (if using 10X buffer) at 4 degrees, 2h or 5min (if using 2X buffer) at room temprature.

Equipement Required
  • 1.5mL Microfuge tubes
  • Pipettes
  • Fridge
