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.

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 advice / comments on the stratage on the data collection of S-nitrosylated protein crystals? The protein crystals did not diffract well with in house X-ray. Thank you for your comments. Uma
