Dear Uma, A very complehensive survey of the state-of-the-art in this topic can be found in the following literature resources: (1) Garman EF. Radiation damage in macromolecular crystallography: what is it and why should we care? Acta Crystallogr D Biol Crystallogr. 2010 Apr;66(Pt 4):339-51.

Maybe you can try different energies hoping that damage is wavelength dependent.  It must be dose dependent though, so you may consider merging short sweeps from multiple crystals. Original message From: Uma Ratu Date: To: CCP4BB@JISCMAIL.AC.UK Subject: [ccp4bb] S

Dear All: I plan to use X-ray crystallography method to study the S-nitrosylated protein structure. The native protein crystals diffracted to 2A with synchrontron. I now have the crystals of S-ntrosylated protein. Since S-NO moiety appears to be unstable to synchrotron radiation, could you advic
