Have you tried microseeding or macroseeding? The original crystals
for my Ph D project only diffracted to ~8 angstroms. Microseeding
gave crystals that eventually diffracted to ~2.0.
Here are two refs that might be useful:
Bergfors, T. (2003). Seeds to crystals. J Struct Biol 142(1): 66-76.
Beyond improvement via 'chemical' means, I would heartily recommend
mutagenesis for crystal packing improvement. I would be glad to help you
with the latter if you're interested.
