A very fast and easy method for the size-selective removal of smaller DNA from larger fragments. By adjusting the PEG and MgCl2 concentration the range of precipitated DNA fragments can be adjusted.
- DNA to be separated
- 30% (w/v) PEG 8000/30 mM MgCl2 (concentration of PEG 8000 can be varied to shift the size of the percipitated DNA)
- TE Buffer, pH 8.0 (10 mM TRIS-HCl, 1 mM EDTA, pH 8.0)
- Centrifuge which can do up to 10.000 rcf (=g)
- Appropriate tubes for the centrifuge
- Mix 50 μL of sample with 150 µL of TE
- Add 100 µL of PEG/MgCl2
