Search OAS:
Unpaired Sequences

>   About
  • Use this form to search for sets of unpaired sequences within OAS.
  • The search fields are not exclusive, so if you pick a combination of fields that does not exist in our database, it will yield no results.
  • All of the unpaired sequences contained within the OAS database can be downloaded by searching without using any attributes.
  • Alternatively, you can query OAS using an example sequence. If a sequence is provided, up to 1,000 sequences with the same V and J germline genes from data sets matching your search parameters will be selected. A single file containing the results will be provided for download.
  • For more help, see the Help page.
