Fellow netters,

Is there anyone out there who has a reproducible protocol for washing and 
re-equilibrating Qiagen columns for re-use such that there is no 
contamination in subsequent elutions?  What is the limit for the number of 
times a Qiagen column can be re-used?  The Qiagen handbook says that the 
resin is only stable for three hours after equilibration.  Is this true?
Any advice for how to stretch our research dollars (francs) greatly
