title: Improved single-strand conformation polymorphism analysis by asymmetric polymerase chain reaction with end-labeled primers.
abstract: An improved form of single-strand conformation polymorphism (SSCP) assay has been developed for the analysis of bovine major histocompatibility complex class II alleles. The method uses asymmetric polymerase chain reaction (PCR) amplification from each of two end-labeled primers to generate individual single-stranded products that are analyzed by electrophoresis in nondenaturing polyacrylamide gels. This technique gives good resolution of labeled single strands derived from 392-bp bovine DRB exon-2 PCR products, without interference from double-stranded products, and enables assignment of SSCP bands to the individual strands of the template DNA. The allelic groupings defined by this method in a panel of test animals were confirmed by independent typing by restriction fragment-length polymorphism.
