A plot of the number of native SAD structures deposited in the Protein Data Bank by X-ray source. Home-source structures include 20 from copper sources (λ = 1.5418 Å) and 31 from chromium sources (λ = 2.2909 Å). The last five years have seen a dramatic rise in synchrotron structures, while home-source structures remain flat.
