Research Projects

Analysis platform for molecular mechanisms and cellular functions

An analysis platform consisting of four components offers a significant expansion of biomedical analysis possibilities at Hochschule Bonn-Rhein-Sieg (H-BRS). A binding analysis device based on microscaled thermophoresis contributes an innovative approach to characterising interactions involving proteins. A multi-mode detection device for UV/Vis, fluorescence and luminescence allows, among other things, a variety of enzyme activity tests and imaging studies in new or improved form. An automated patch clamp system and a system for solid-supported membrane (SSM)-based electrophysiology for high-resolution transporter studies provide the equipment basis for expanding research into membrane transport processes and other molecular mechanisms of disease development.
