FIZ Karlsruhe, a European information services provider and European partner of STN International, has announced the launch of the PCTGEN database, a new source of nucleotide and amino acid sequence information. Containing sequence and patent application information submitted electronically to the World Intellectual Property Organization (WIPO), PCTGEN includes both the nucleotide and peptide sequences themselves, as well as associated bibliographic data as provided by patent applicants. More specifically, records include the following fields: accession number, title, document type, molecule type, patent assignee, patent and application information, organism species, sequence, sequence length, and feature table. Jointly produced by FIZ Karlsruhe and WIPO, PCTGEN currently contains around 1.5 million records from August 2001 to date, including 1.2 million nucleic acid and 0.3 million peptide sequences. STN International can be accessed by dialing directly into STN Classic, the proprietary online service, utilizing the client software STN Express with Discover!; or via STN on the Web using a standard web browser. Both access modes provide searchers with a set of dedicated sequence search tools. Sequence searching in PCTGEN will also be integrated into STN on the Web's Sequence Search Assistant, an interface designed for those unfamiliar with traditional command-line searching.
