High Pressure Cryocooling of Capillary Sample Cryoprotection and Diffraction Phasing at Long Wavelengths
Overview
Crystal cryocooling is usually employed to reduce radiation damage during, X-ray crystallography. Recently, a high-pressure cryocooling method has, been developed which results in excellent diffraction-quality crystals, without the use of penetrative cryoprotectants. Three new developments of, the method are presented here: (i) Xe-He high-pressure cryocooling for Xe, SAD phasing, (ii) native sulfur SAD phasing and (iii) successful, cryopreservation of crystals in thick-walled capillaries without, additional cryoprotectants other than the native mother liquor. These, developments may be useful for structural solution of proteins without the, need for selenomethionine incorporation and for high-throughput protein, crystallography.
