We have developed a simple, straightforward procedure to isolate exons from cloned human genomic DNA. The method is PCR based and relies upon the conservation of splice-site sequences and the frequency of Alu repeat elements in the genome to capture coding sequences. We designed two different sets of primers: a primer from each end of the Alu element and primers with the 5' or 3' splice-site consensus sequences. Putative exons were amplified by PCR using YAC DNA as starting material. We applied Alu-splice PCR to two overlapping YACs, 72H9 and 860G11, from human chromosome 21. Sequence and northern analysis of 37 initial clones resulted in the identification of five novel exons.
