UniSTS was a database of sequence tagged sites (STSs), derived from STS-based maps and other experiments. All data from this resource have been moved to the Probe database. You can retrieve all UniSTS records by searching the probe database using the search term "unists[properties]". Additionally, legacy data remain on the NCBI FTP Site in the UniSTS Repository (ftp://ftp.ncbi.nih.gov/pub/ProbeDB/legacy_unists).
