Try looking in the "Chromatofocusing" booklet from Pharmacia. This is
an old booklet and I don't know if they still publish it. This booklet
talks about a lot of the basics so you should be able to start with
the general stuff and modify them to suit your needs. There is also a
little bit of information in "Protein Purification" by Scopes (in both
2nd and 3rd edition but the 3rd edition is better).

Hope this info helps
