Protein chromatography

I have some good experience with a Pharmacia GradiFrac system for low 
pressure chromatography. The only problem I encountered was that their 
P50 pump is no good for crude feeds (like cytosol). In such cases it is 
best to use a peristaltic pump for loading and connect the column to the 
GradiFrac system for washing and elution. I suppose you will have the 
same problem with any membrane or piston pump. As far as columns go, I 
would never get anything but the Pharmacia ones. Oh, and make shure you 
get the ones that can be cooled, the additional cost is low and you never 
know when you will need it.
