RNA Quality control The assessment of RNA integrity is a critical ﬁrst
step in obtaining meaningful gene expression data. Working with low-
quality RNA may strongly compromise the experimental results of
downstream applications which are often labour-intensive, time-
consuming, and highly expensive. Using intact and integer RNA is a key
element for the successful application of modern molecular biological
methods, like qRT-PCR or micro-array analysis. To verify RNA quality
nowadays commercially available automated capillary-electrophoresis
systems are available which are on the way to become the standard in
RNA quality assessment. Proﬁles generated yield information on RNA
concentration, allow a visual inspection of RNA integrity, and
generate approximated ratios between the mass of ribosomal sub-units.

The prominent and still growing place taken by real-time quantitative
PCR in applied and fundamental research and clinical diagnostics
almost appears obvious. However, it is clear that contributions made
by various scientists and companies in the field during the last
decade rendered this technology useful and affordable for many users.

Importantly, the qPCR domain is still in constant evolution, making it
sometimes hard to stay informed about new methodological approaches or
original studies using the real-time PCR. Therefore, we have scheduled
a one day "Benelux qPCR Symposium" on October 6th 2008, giving the
opportunity to the scientific community to get informed and discuss
various aspects of real-time PCR (including but not limited to new
applications, assay optimization and validation, new technologies,
etc.). Scientific talks, posters sessions and industrial booths will
be at the menu.

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. ]
