Refolding problem

[Joerg Freigang]

I am trying to refold a protein belonging to the IGSF from inclusion
bodies. The protein contains two disulfide bonds and a his-tag. I tried
the refolding procedure developed by R. Rudolph for Fab-fragments as
well as some other standart refolding procedures, but I couldn't get any
detectable amounts of monodispers protein.
Any suggestions what the problem could be and what else should be tried?
Even 1 % of correctly folded protein would be enough.
