  • Title: Ligation detection reaction-TaqMan procedure for single nucleotide polymorphism detection on genomic DNA.
    Author: Borodina TA, Lehrach H, Soldatov AV.
    Journal: Anal Biochem; 2004 Oct 15; 333(2):309-19. PubMed ID: 15450807.
    Abstract:
    In this article, we describe a genotyping approach applicable to both individual and multiplexed single nucleotide polymorphism (SNP) analysis, based on a ligation detection reaction (LDR) performed directly on genomic DNA. During the ligation, the biallelic state of the SNP locus is converted into a bimarker state of ligated detector oligonucleotides. The state of the markers is then determined by a 5'-nuclease assay (TaqMan) with universal fluorescent probes. The LDR-TaqMan method was successfully applied for the genotyping of 30 SNP loci of Arabidopsis thaliana. The technology is cost-effective, needs no locus-specific optimization, requires minimal manipulations, and has very good potential for automation.
