I don't suppose there are any coupling procedures that work in Urea or

Alternatively could you make a fusion protein (more work I know :( )
then bind the fusion part to it's normal affinity column even in
denaturant i.e. His, GST, MBP etc. 

The problem with being on the cutting edge is that you occasionally get 
sliced from time to time....
