ELXR: a resource for rapid exon-directed sequence analysis

ELXR (Exon Locator and Extractor for Resequencing) streamlines the process of determining exon/intron boundaries and designing PCR and sequencing primers for high-throughput resequencing of exons. We have pre-computed ELXR primer sets for all exons identified from the human, mouse, and rat mRNA reference sequence (RefSeq) public databases curated by the National Center for Biotechnology Information. The resulting exon-flanking PCR primer pairs have been compiled into a system called ELXRdb, which may be searched by keyword, gene name or RefSeq accession number.
