STC map across the 1.1-Mb human α/δ T cell receptor locus. This diagram depicts a BAC contig constructed by using a 1,071-kb sequence from the T cell receptor α locus to query the STC database. The sequence was masked for repeats (http://repeatmasker.genome.washington.edu/) and used to search the TIGR STC database (http://www.tigr.org/tdb/humgen/bac_end_search/bac_end_search.html) which, at the time, contained around 310,000 sequences. BAC clones shown as solid lines had both end sequences available in the STC database; dotted lines represent BAC clones where only one end sequence was available The arrow-head points in the direction of the unsequenced end, and the insert size is arbitrarily set at 150 kb. The bottom scale depicts the length in kb of this locus.
