Cutting Qiagen miniprebs??

I've never had problems with digestion, but try this:
1) Spin down the bacterial lysate for an extra 5 minutes.
2) Use the optional PB wash.
3) Give the columns a second wash with PE buffer.
4)  Make extra sure to get the columns dry after the PE washes.  
Spin the columns for a minimum of 1 minute, and 2-3 minutes if you 
are not in a big hurry.Bjoern Voldborg wrote:
