Title: Rapid and Efficient cDNA Library Screening by Self-Ligation ofInverse PCR Products (SLIP)

Abstract

The production of comprehensive cDNA clone collections is an important goal of the human and model organism genome projects. cDNA sequences are used to determine the structures of transcripts, including splice junctions, polyadenylation sites, and 5' and 3' untranslated regions (UTRs). cDNA collections are also valuable resources for functional studies of genes and proteins. Expressed Sequence Tag (EST)sequencing is the method of choice for recovering cDNAs representing a majority of the transcripts encoded in a eukaryotic genome. However, EST sequencing samples a library at random, so it realizes diminishing returns as the project progresses. To drive cDNA collections toward completion new methods are needed to recover cDNAs representing specific genes and alternative transcripts, including transcripts with low expression levels. We describe a simple and effective inverse-PCR-based method for screening plasmid libraries to recover intact cDNAs for specific transcripts. We tested the method by screening libraries used in our Drosophila EST projects for 153 transcription factor genes that were not yet represented by full-length cDNAs. We recovered target-specific clones for 104 of the genes: 46 exactly match, 30 improve and 28partially match current gene annotations. Successful application of the screening method depends on cDNA library complexity and quality of the genemore » models. The approach should be effective for improving cDNA collections for other model organisms and the human. It also provides a simple and rapid method for isolating cDNAs of interest in any system for which plasmid cDNA libraries and complete or partial gene sequences are available.« less
