Ultra-rapid melting curve analysis on beads for high-throughput genotyping of single nucleotide polymorphism

• This report describes a rapid solid-phase melting curve analysis method based on dynamic allele-specific hybridization (DASH) for single nucleotide polymorphism (SNP) genotyping. Beads with DNA duplexes are immobilized on the surface of a microheater chip. SNP on PCR products were scored, illustrating the sensitivity and robustness of the system. Single-bead detection and multiplexing were performed with a heating rate more than 20 times faster than conventional DASH. Hence, analyses that took more than 15 minutes could be performed in less than 1 minute, enabling ultra-rapid SNP analysis.
