| The nucleotide sequence files available below are those used to the produce the plasmid vector, viral and bacteriophage maps contained in New England Biolabs Catalog as well as the tables containing the locations of sites. Maps and location of sites are PDF files. Sequence files are in FASTA or/and GenBank format. Detailed frequencies with which restriction endonuclease sites occur in commonly used DNA molecules can be found on Frequencies of Restriction Sites. These sequences are provided as a convenience to the scientific community and New England Biolabs is not responsible for any inaccuracies present in the sequences. |
