Anomalous Scattering For Atoms in the Periodic Table:

Use the hyperlinks to obtain the frequency of use in protein structure phasing, the name of the compounds and the suppliers and their addresses for each element. The frequencies reported here are the number of structures solved using a particular compound. These are derived from "Macromolecular Structures 1991-1995, Atomic Structures of Biological Macromolecules reported during 1990,1991,1992,1993. (W.A. Hendrickson & K. W|thrich eds.) Current Biology Ltd. (London)."
