In my experience positively charged detergents like CTAB can dissolve  
nuclei very well (better than SDS) while at the same time are generally  
mild (milder than OG or DM) to proteins. Whether or not the interaction  
that your friend is interested in is maintained under these conditions  
he/she will have to find out.
