Long-range PCR based sequencing of the highly homologous genes, SFTPA1 and SFTPA2.

In humans, Surfactant Protein A exists as two highly homologous genetic isoforms, SFTPA1 and SFTPA2. Mutations in these two genes are associated with idiopathic pulmonary fibrosis (IPF) and lung cancer. We have developed a Sanger DNA sequencing assay which utilizes long-range PCR to detect mutations in these two genes.

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.
