High-Resolution Melting (HRM) analysis is a relatively new, post-PCR analysis method used to identify variations in nucleic acid sequences. The method is based on detecting small differences in PCR melting (dissociation) curves. It is enabled by improved dsDNA-binding dyes used in conjunction with real-time PCR instrumentation that has precise temperature ramp control and advanced data capture capabilities. Data are analyzed and manipulated using software designed specifically for HRM analysis.
