Due to maintenance work, this service and ftp://ftp.expasy.org will be unavailable from Tuesday August 23rd 18:00 until Wednesday August 24th 08:00 CEST. Apologies for the inconvenience.
This BLAST service was shut down in March 2022.

You can find most of the protein databases that were available here at the UniProt BLAST service.
For nucleotide databases we recommend that you use the EBI BLAST service or the NCBI BLAST service.
