WebSerial crystallography is an ideal method for collecting diffraction data of proteins at room temperature, where the onset of radiation damage from the X-ray beam is rapid. Serial crystallography experiment set up at Beamline ID7B2, MacCHESS. One major bottleneck in the protein crystallography experiment is collection of a complete dataset ... WebCrystallography ISSN 0907-4449 Radiation damage in macromolecular ... crystalline samples during the experiment is a problem that ... it often necessitates the use of many crystals to assemble a complete data set, because the crystalline order of the sample is damaged and decreases during the experiment and thus the diffracted intensity fades. ...

WebThe aim of x ray crystallography is to obtain a three dimensional molecular structure from a crystal. A purified sample at high concentration is crystallised and the crystals are exposed to an x ray beam. The resulting diffraction patterns can then be processed, initially to yield information about the crystal packing symmetry and the size of the repeating unit that … Webproblem. Finally, the phase problem may be formulated as one in constrained global op-timization. A method for avoiding the countless local minima in order to arrive at the …
