Engineering BioBrick vectors from BioBrick parts/Restriction digest
- DNA Engine Peltier Thermal Cycler (PTC-200) from MJ Research, Inc. (now Bio-Rad Laboratories, Inc., Hercules, CA).
- 1X NEB2 buffer
- 100 μg/mL BSA
- 1 μL BioBrick enzyme 1
- 1 μL BioBrick enzyme 2
deionized, sterile H2O to 50 μL
Vortex all reagents before use.
- Add appropriate amount of deionized H2O to sterile 0.6 mL tube
- Add restriction enzyme buffer.
- Add BSA.
- Add DNA.
- Add each enzyme.
Also, the enzyme is in some percentage of glycerol which tends to stick to the sides of your tip. To ensure you add only 1 μL, just touch your tip to the surface of the liquid when pipetting.
- Incubate for 2 hours at 37°C.
- Incubate for 20 mins at 80°C to heat inactivate enzyme.
This step is sufficient to inactivate even Pst I.
- Incubate 4°C until you pull the reaction out of the thermal cycler.
