Dear CCP4 Community, We are trying to find protein or virus crystals that diffract to reasonably high resolution (2.5 Angstroms or better) and that are very radiation sensitive at room temperature. "Very radiation sensitive" in this case means that the diffraction dies after a few frames, for crystals that don't contain heavy atoms. (If you're calculating doses, the diffraction should die after 0.1 MGy or less).
Typically, these crystals have high solvent contents (80% or more) and weak packing interactions. So, we would be very interested in collaborating if you have: - crystals that you know are very radiation sensitive at room temperature; and/or - crystals with solvent contents >80%. Any advice/suggestions would be appreciated! Rob -- Robert E. Thorne Professor of Physics 529A Clark Hall Cornell University Ithaca, NY 14853 phone: (607) 255 6487 fax: (607) 697 0400
