Another suggestion that comes to mind is crosslinking via Cys, are you
purifying under reducing conditions ? Or since you have inclusion
bodies they're in general not correctly folded hence expose
hydrophobic regions and can interact with other proteins, to avoid
unspecific interaction add >20% glycerol to your lysis buffer.
