Planar, freestanding lipid membranes for X-ray structure analysis — •André Beerlink — Institut für Röntgenphysik, Universität Göttingen, Friedrich-Hund-Platz 1, 37077 Göttingen, Germany

Since the development of planar, freestanding lipid membranes in the early 1960s by Müller and Rudin, this model membranes have been used for many, especially physiological, experiments. X-ray structure analysis has always been limited to solid supported membrane systems in uni-, bi- or multilamellar phase. For the combination of these two techniques, namely structure analysis of planar, freestanding membranes, improvements of this model membrane system have to be done. We mainly developed the stability of membranes with new types of microstructured apertures and the access for the X-ray beam so that first experiments could be done. Fututre work can open a broad field of simultaneous analysis of physiological and structural information of model membranes.
