Abstract

Real-time PCR high-resolution melting assays are a method for the identification of single nucleotide polymorphisms (SNPs). The assay is performed by amplifying a short DNA fragment using a specific primer pair flanking a target SNP in the presence of a high-resolution melting dye. The HRM analysis of amplicons groups the samples based on the differences in the melting temperature and the shape of the melt curves, facilitating a convenient genotyping of samples. This chapter describes the steps and considerations of real-time PCR HRM assay standardization.
