Reverse phase is very harsh treatment for proteins if you
want to preserve activity. You may just want to try it and see
how much activity you recover after passing your sample
through a reverse phase column.
Another thing to try is Hydrophobic Interaction Chromatography
(HIC) which is apparently much more friendly to proteins with
biological activity. You load your sample in high salt conditions
and elute with low salt. Lots of columns to choose from. You might
consider a kit to test the various types.
I hope that is helpful.
