Quick Ligation Protocol (M2200)
Protocols.io also provides an interactive version of this protocol where you can discover and share optimizations with the research community.
(Quick Ligase should be added last. Note that the table shows a ligation using a molar ratio of 1:3 vector to insert for the indicated DNA sizes.)
Use NEBiocalculator to calculate molar ratios.
20 μl REACTION
Quick Ligase Reaction Buffer (2X)*
Vector DNA (4 kb)
50 ng (0.020 pmol)
Insert DNA (1 kb)
37.5 ng (0.060 pmol)
to 20 µl
2. Gently mix the reaction by pipetting up and down and microfuge briefly.
3. Incubate at room temperature (25°C) for 5 minutes.
4. Chill on ice and transform 1-5 µl of the reaction into 50 µl competent cells. Alternatively, Store at -20°C.
5. Do not heat inactivate – heat inactivation dramatically reduces transformation efficiency.
