Dear
reader,
We are happy to announce the first newsletter of BioDetection
Systems offering you an overview of news on ‘biodetectors’. In our newsletter
we will inform you about the state-of-the-art of innovative biological detection
systems in the analytical world, including new applications and validation of
existing methods. With increased interest and use of these assays in food-,
environmental-, pharmaceutical-, public health and clinical analysis we will
have ample material for our issues that so far are planned to appear three to
four times a year. Most news items will be linked to BDS’ homepage, which we
hope will become an important source of information on these innovative technologies.
Please do not hesitate to contact us with questions, comments, ideas and news
items. We wish you pleasant reading.
With best regards,
Peter
Behnisch and Bart van der Burg This letter contains the
following topics:
At August
15, preceding the Dioxin 2008 conference in Birmingham, England, BDS will organise
the 3rd International BioDetectors Conference in Amsterdam. This annually recurring
event has attracted in the last two years more than 70 participants from all
over the world. In contrast to previous years, the 3rd conference will be one
day only with a morning program of presentations by well-known experts in the
field of BioDetectors for environmental, feed/food, human biomonitoring, and
doping. In the afternoon there will be a possibility to visit BDS’ laboratories
and demonstrations of a range of CALUX technologies for different applications
will be given. In Spring 2008 BDS will launch a call for abstracts and information
about how to register for the 2008-conference.
BDS
is happy to announce the establishment of various new global partners to be
able to meet the increasing demands and to further improve local services. A
listing of all BDS’ global partners can be viewed at our homepage. click
here for list
There will be various possibilities to meet BDS personnel early
in 2008. Among that there will be seminars in various countries. If you are
interested in attending one of these seminars, please refer to the contact details
given in the upcoming events section. If you are interested in more direct information
by BDS, please contact BDS or one of our global partners.
Reference materials have been generated for food and feed
analysed for dioxins and dioxin-like PCBs. The materials have been analysed
by 21 DR CALUX laboratories and 2 HRGC/HRMS laboratories. Prices are: one for
240 €; three for 590 €. A complete listing of products can be viewed at our
homepage. click

Panel of CALUX cells
Through our continuous R&D
activities we now have expanded the panel of CALUX cell lines extensively. These
assays can be used for a wide variety of applications and in coming issues of
BioDetectors we will be presenting application notes to give you a flavour of
what these cell lines could mean for your work. The extension of this highly
standardised panel of reporter cell lines will be a continuing activity in the
coming years, and already several new assays are currently being developed (as
indicated in white). Please contact us for further information on any of these
assays. We would be happy to discuss your specific needs.

This study on estrogenic activity in river water showed that
the results obtained by the ER CALUX assay are consistent with that of an in
vivo fish study using the same water samples.

This study determines the mechanism of interference
of glucocorticoids in the DR CALUX assay. This information is used to guarantee
the selectivity of the assay using new matrices, such as clinical material.
