  1. Import a sequence .txt file. The sequence formats supported by STNext include plain text, FASTA, GENBANK, and EMBL. You may also download or edit the sequence after import.
  2. Open at least one of the following files on the Databases tab:
    • DGENE
    • PCTGEN
    • USGENE
  3. Upload the sequence.

Note: Prior to searching sequences in CAS REGISTRY, download and install the CAS Registry BLAST® client. See Using CAS Registry Blast.
