No refs that I have on hand but depending on the protein, one of the
two extreme approaches should work:
1. Quickly dump and mix your sepharose-bound protein into
100-300 column volumes of a solution without denaturant and let
sit for an hour or so.
2. Run slow (20-30 column volumes) gradient from 100% to 0%
denaturant through a column.
Both done better at RT but there are, I believe, some examples
of #2 working better in the cold room.
