Bionas GmbH (Rostock, Germany) and Solvay Pharmaceuticals Research Laboratories (Weesp, The Netherlands) announce that the Bionas® 2500 analyzing system has been recognized to be a valuable tool for target validation studies.
Bionas GmbH (Rostock, Germany) and Solvay Pharmaceuticals Research Laboratories (Weesp, The Netherlands) announce that the Bionas® 2500 analyzing system has been recognized to be a valuable tool for target validation studies.
"It is known that angiotensin 1-8 (angiotensin II) acts via two receptors. The AT1 receptor mediates vasoconstriction upon stimulation, whereas the AT2 receptor is implicated in hypotensive effects. However, the mechanism through which angiotensin 1-7 induces its powerful hypotensive effect were unclear," explains Dr. Eric Ronken, Principal Scientist at Solvay.
On-line monitoring of endothelial cell physiology and its changes upon challenges by angiotensin 1-7 helped in delineating the mechanism of action by this peptide. The Bionas® 2500 analyzing system is well suited for such experiments, as it measures cellular acidification, oxygen consumption and cell adhesion simultaneously in a label-free and non-invasive way. "The Bionas system allows us to extend and optimize target validation studies by bringing the targets back into their physiological context", says Dr. Eric Ronken.
The Bionas 2500 analyzing system gives a complete overview over the physiologic state of cells. It can be used to discriminate between different signal transduction pathways allowing target validation studies at an early stage in the drug discovery process. Recently, Bionas announced the usefulness of its device to predict liver toxicity in primary human hepatocytes and standardized HepG2 cells.
About Bionas - http://www.bionas.de
Bionas GmbH, situated in Rostock, Germany, specializes in analyzing systems and services for in-vitro profiling the metabolic activity of cells to understand cellular function. Bionas® 2500 analyzing system measures extracellular acidification, oxygen consumption and cell adhesion in a label-free and non-invasive way and can be applied to various cell types including primary cells. The readout is carried out continuously and can be watched online. Main applications include drug profiling, lead optimization, pharmaco kinetics, early toxicology programs, ADME/Tox, chemosensitivity testing, toxicological testing of chemical substances (REACH) and cell culture monitoring/optimization. Micronas Holding GmbH and GENIUS Venture Capital GmbH fund the company.

You can combine search terms with and, or and/or not, e.g. Philo not logy.
You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).
Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.
You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).
If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
