PCR Purification
Materials
- 1.5 ml microcentrifuge tubes
- 2 ml collection tube
- QIAquick columns
- Qiagen Buffer PB
- Qiagen Buffer EB
- Qiagen Buffer PE
- DNA mixture from PCR
Protocol
- Add 5 volumes of Qiagen Buffer PB to 1 volume of PCR product.
- Put a QIAquick spin column into a 2ml collection tube.
- Apply the mixture to the QIAquick column to bind the DNA and centrifuge for 30 to 60 seconds at 13,000 rpm.
- Discard flow-through. Add 0.75 ml of Buffer PE to the spin column to wash and centrifuge for 30 to 60 seconds at 13,000 rpm.
- Discard flow-through and centrifuge for another 1 minute at 13,000 rpm.
- Place QIAquick spin column into a clean 1.5 ml microcentrifuge tube.
- Add 50 µl Buffer EB to the center of the membrane of spin column and centrifuge for 1 minute at 13,000 rpm.
- If analysing purified DNA using gel, add 1 volume of Loading Dye to 5 volumes of DNA.
- Store the PCR product either at 4°C or at -20°C.
