qPCR NEWS - January 2008 - Special Topic: High Resolution Melt




Dear researcher,
dear Gene Quantification page reader,

Our newsletter informs about the latest news in quantitative real-time
PCR (qPCR and qRT-PCR), which are compiled and summarised on the Gene
Quantification homepage. The focus of this newsletter issue is:

- HRM - High Resolution Melt
- updates on qPCR INFOPORTAL
- qPCR application workshops in 2008

--------------------------------------------------------------------------------

High Resolution Melting (HRM)

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
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

With HRM, these and other applications are done using low-cost generic
dyes where previously custom labeled probes such as TaqMan® or
fluorescence resonance energy transfer (FRET) probes were required.
HRM is thus a simpler and much more cost-effective way to characterize
samples.

WORKSHOP

TATAA Biocenter Germany - qPCR Application workshops

At the TATAA Biocenter Germany we offer qPCR application workshops,
the 3-day Core Module and a 2-day Biostatistics Module. qPCR courses
are held in regularly in Göteborg, Sweden, in English and in Freising-
Weihenstephan, Germany, in German and English, and in Prague, Czech
Republic in English and Czech.
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 courses are held in cooperation with the Institute
of Physiology, located at the Technical University of Munich, in
Freising-Weihenstephan, near Munich, very close to the Munich Airport
(MUC). For more information and to register for the qPCR application
workshops, please see our web page: [Only registered users see links. ]
