Well, I've had success working at 2M urea, getting a GST-fusion protein on
and off beads and cutting successfully with (human) thrombin. I had to
break up inclusion bodies at 8M urea, dilute to 2M, and carry on as usual.
Of course, the question of solubility of your target protein then becomes
the main problem.
