Abstract
OBJECTIVES
A reliable high-throughput assay system is necessary for the analysis of the ever-increasing numbers of single-nucleotide polymorphisms (SNP) relevant to genetic screening studies. We describe an assay suitable also for large-scale screening programs.
DESIGN AND METHODS
The one-step assay is based on asymmetric PCR amplification of the target sequence and subsequent time-resolved fluorescence measurement. Asymmetric amplification results in a single-stranded PCR product that is detected in the amplification vessel with a highly sensitive, homogeneous hybridization method.
RESULTS
A dual label, homogeneous high-throughput platform for nucleic acid sequence analysis was developed and validated using a C/T single-nucleotide polymorphism in the insulin gene as a model analyte and applied also to two other SNP-assays (poliovirus receptor A/G-polymorphism and CD86-gene exon 2 A/G-polymorphism).
CONCLUSIONS
The described high-throughput genotyping technology is very competitive in price, simple in design and easily applied to any analyte sequence.
