to PPT or not to PPT

Our experience with EtOH ppt has been less than pleasing and we  have=20
reverted back to column purification.  We didn=92t have any problems with=
T-Blobs but the first 50-60 bp were virtually unusable.  If you can live=20
with this than go with the EtOH ppt if you=92re doing only a few samples. =
For a full run we have found that both methods take about the same amount=
of time and the extra usable data aquired with the column method is worth=
the extra expence.

Hope this helps :-)
