High Resolution Melting (HRM) is a novel, homogeneous, close-tube, post-PCR method, enabling genomic researchers to analyze genetic variations (SNPs, mutations, methylations) in PCR amplicons. It goes beyond the power of classical melting curve analysis by allowing to study the thermal denaturation of a double-stranded DNA in much more detail and with much higher information yield than ever before. HRM characterizes nucleic acid samples based on their disassociation (melting) behavior. Samples can be discriminated according to their sequence, length, GC content or strand complementarity. Even single base changes such as SNPs (single nucleotide polymorphisms) can be readily identified.

The most important High Resolution Melting application is gene scanning - the search for the presence of unknown variations in PCR amplicons prior to or as an alternative to sequencing. Mutations in PCR products are detectable by High Resolution Melting because they change the shape of DNA melting curves. A combination of new-generation DNA dyes, high-end instrumentation and sophisticated analysis software allows to detect these changes and to derive information about the underlying sequence constellation.
HRM Applications => new papers
The introduction of HRM has renewed interest in the utility of DNA melting for a wide range of uses, including:
Mutation discovery (gene scanning)
Screening for loss of heterozygosity
DNA fingerprinting
SNP genotyping
Characterization of haplotype blocks
DNA methylation analysis
DNA mapping
Species identification
Somatic acquired mutation ratios
HLA compatibility typing
Association (case/control) studies
Allelic prevalence in a population
Identification of candidate predisposition genes

High Resolution Melting Dyes & probes
http://hrm-dyes.
The secret of High Resolution Meling (HRM) analysis is to monitor this process happening in real-time. This is achieved by using saturating fluorescent dye. HRM dyes are known as intercalating dyes bind specifically and in high amount (= saturating dye, except SYBR Green) to double-stranded DNA and when they are bound they fluoresce brightly. In the absence of double-stranded DNA they have nothing to bind to and they only fluoresce at a low level (estimations are between 1-4% false positive fluorescence)

online translation
Since October 2008 we provide an online translation service of the Gene Quantification pages to several languages. Please recognize this is an automatic and robotic based translation service, and therefore we can give NO guarantee about the generated content. It should help to understand the "rough" content of the Gene Quantification pages, but still the original is the ENGLISH version:

qPCR WORKSHOP
BioEPS GmbH / TATAA Biocenter Germany - qPCR Application workshops
At the TATAA Biocenter Germany we offer qPCR application workshops, a 3-day qPCR Core Module and a 2-day qPCR Biostatistics Module. All courses are held regularly in Göteborg, Sweden, in English and in Freising-Weihenstep
Depending on the occasion the workshop language and the different prices may apply. Further customized workshops and specialized trainings will be held as well across Europe and world-wide.
TATAA Biocenter Germany workshops are held in cooperation with BioEPS GmbH, located at the campus of the Technical University of Munich, in Freising-Weihenstep
