Abstract excerpt
Allele-specific oligonucleotides are used widely for the detection of single point mutations in genes. A modification of this assay based on competition has been developed for detection of the Z mutation of alpha 1-antitrypsin (alpha 1-AT). The normal alpha 1-AT allele is referred to as M, and the Z mutation arises from a single base substitution. Amplified DNA products corresponding to homozygous M, heterozygous...
