Chemical-mediated Melting Curve Analysis for Genotyping of Single Nucleotide Polymorphisms
نویسندگان
چکیده
This report describes a new microfluidic solid-phase chemical-mediated melting curve analysis method for Single Nucleotide Polymorphism (SNP) genotyping. The method is based on allele-specific denaturation of DNA duplexes upon exposure to dynamic chemical gradient. DNA duplexes conjugated on beads are captured in a microfluidic gradient generator device. The device is designed with dams, keeping the beads trapped perpendicular to the gradient generating channel. Upon exposure to a gradient of formamide or urea, rapid denaturing profile is monitored in real time or in a single end-point analysis.

Genotyping common SNP and a microsatellite sequence closely linked to waxy gene in rice by DNA based markers
The potential of different DNA based molecular markers was examined for the detection of single nucleotide polymorphism (SNP) in the waxy gene and a microsatellite (SSR) sequence closely linked to it in a collection of rice varieties. DNA was extracted from leaf samples of 68 different rice cultivars by the CTAB method and specific primers were designed for the amplification of waxy gene and SS...

Genotyping Parkinson disease-associated mitochondrial polymorphisms.
OBJECTIVE The purpose of this study was to establish a system for rapidly detecting single nucleotide polymorphisms (SNPs) in mitochondrial DNA (mtDNA) using hybridization probes and melting temperature (T(m)) analysis. This technology should prove useful for population-based studies on the interaction between genetic factors and environmental exposures and the risk of Parkinson disease (PD). ...
متن کاملHigh-resolution melting curve analysis of genomic and whole-genome amplified DNA.
BACKGROUND High-resolution melting curve analysis is an accurate method for mutation detection in genomic DNA. Few studies have compared the performance of high-resolution DNA melting curve analysis (HRM) in genomic and whole-genome amplified (WGA) DNA. METHODS In 39 paired genomic and WGA samples, 23 amplicons from 9 genes were PCR amplified and analyzed by high-resolution melting curve anal...
