A 350-kb YAC containing mouse genomic DNA was gel-purified and used as the target DNA for the 3'-terminal exon trapping strategy. A novel direct ligation/transfection approach was employed to increase the efficiency of trapping 3'-terminal exons from recombinant vector-derived chimeric mRNA. The resulting RT-PCR product was then used to generate a plasmid library. Randomly chosen individual subclones from this library were sequenced, and the results indicate that 86% met sequence criteria characteristic of 3'-terminal exons, whereas 14% were background from identified sources. PCR mapping efforts suggest eight putative last exons present within this YAC, whereas RT-PCR studies demonstrate that three reside within valid expressed sequences.}, URL = {http://genome.cshlp.org/content/4/6/322.abstract}, eprint = {http://genome.cshlp.org/content/4/6/322.full.pdf+html}, journal = {Genome Research} }
