Method from primary and secondary reagents

Primary & secondary Reagents Required including controls

• Ligase buffer (10X or 2X)
• DNA for ligation
• T4 DNA ligase
• milliQ water

Method including controls

Add to a sterile 1.7ml Eppendorf

1. Roughly an 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
