at the Fred Hutchinson Cancer Research Center Blocks WWW server.

Search your protein or DNA sequence against a Blocks Database. [Help] [Example of output]

- Enter your email address if you want the results through email :

- Select database to search:
  We recommend searching both Blocks and Prints. Blocks has automatically-generated blocks, while Prints has hand-crafted blocks.

- Optionally select cutoff expected value:
- Optionally select amount of output:
- Optionally force query sequence type:

- Additional optional search parameters for a DNA query:
  - Strands to search:
  - Genetic code:

- Enter your protein or DNA query sequence in FASTA, EMBL or GENBANK format:

  Response time will vary depending on query sequence length and type and may take several minutes. Our system can process a maximum of about 25 amino acids per second. This means a protein query 300 amino acids in length will take at least 12 seconds while a DNA query 1100 nucleotides in length translated in 6 frames will take at least 1.5 minutes. Please be patient, or supply an email address.

  You can also search Blocks using different algorithms with Reverse PSI-BLAST, IMPALA, Ematrix or Identify.
  You can search other protein family collections with InterPro, CD-Search or eBLOCKS.
