I. Polikarpov et al., THE ULTIMATE WAVELENGTH FOR PROTEIN CRYSTALLOGRAPHY, Acta crystallographica. Section D, Biological crystallography, 53, 1997, pp. 734-737
This paper describes an analysis of the optimum choice of the X-ray wa
velength for macromolecular diffraction data collection. It is shown t
hat there is no ultimate X-ray wavelength for protein crystallography
and that the optimum wavelength depends to a large extent on the size
of the protein crystal. It also depends on instrumental factors, such
as efficiency of the detector for a particular wavelength and spectral
density of the synchrotron radiation. Estimates of the optimum wavele
ngth as a function of crystal size are given.
