My immediate reaction is to suggest that you try to find a
way of getting your bugs to express soluble protein.
Protein refolding can be a painful business, some refold
easily, some don't, and I don't think there is a universal
methods that can guarantee that your protein refolds. The
best thing perhaps is to look at some reviews:
Eliana De Bernardez Clark
Current Opinion in Biotechnology 1998, 9:157-163.
Hauke Lilie, Elisabeth Schwarz, Rainer Rudolph
Current Opinion in Biotechnology 1998, 9:497-501.
It would be also useful to have a look at the following:
I'm not suggesting that you buy the products, as I've tried
it and it was only partially successful (similar in
effectiveness to refolding in 1M arginine). There are,
however, some useful ideas about the process of refolding of
protein. Good luck (and you'll need it!).
