Characteristics of currently-available reference datasets for use in CD analyses, and the servers on which they are available. The final column indicates the types of proteins for which the dataset may be best suited. The individual protein spectral data comprising the SP17521 and SMP18022 datasets can be downloaded from the PCDDB35.
