11. Remove a spin column from the bag and snap off the
tab at the tip. Place the spin column inside a 2 ml col-
lection tube. Transfer the resuspended matrix from
the previous step to the spin column. Puncture a
hole in a spin column cap with a small, sharp object
and cap the column with it. Spin 30 seconds in a
microcentrifuge at 12–14,000 x g. Remove the spin
column from its microcentrifuge tube, discard the
wash buffer at the bottom of the tube and replace
the filter in the same tube.
12. Add 500 µl of wash buffer and spin 30 seconds in a
microcentrifuge at 12–14,000g. Remove spin column
and discard Wash Buffer. If isolating DNA from an
EndA+ strain do two additional 500 µl wash steps.
13. Replace the spin column in the tube and spin an
additional 2 minutes at maximum speed to remove
any residual wash buffer.
14. Transfer the spin column to a clean 2 ml microcen-
trifuge tube. Add 600 µl of water or TE to the matrix.
Spin for 2 minutes in a microcentrifuge and discard the
spin column containing the matrix. Store plasmid
DNA at -20 °C.
