Search CDRs

>   About
  • Search through the complementarity determining regions of the antibodies stored in SAbDab.
  • Use the 'Get all CDRs' tab to get a list of all CDRs from all antibody structures.
  • Choose from five different definitions: Chothia, contact, IMGT, Kabat, and North.
  • Search for a subset of CDRs by attribute - such as species, experimental method, resolution, length, sequence etc.
  • Generate a list of CDRs that have unique sequences (for each sequence, the structure with the best resolution is kept).
  • For more help, see the About page.
