This volume contains the proceedings of the FEBS Sym posium on the Biochemistry of Membrane Transport, which was held at the Swiss Institute of Technology, Zlirich, July 18-23, 1976. Of the speakers invited or iginally, only five could not attend the meeting, and of the lectures given, all but one of the texts are published here. Thus, this volume gives a faithful ac count of the way the meeting was originally conceived and actually took place. This Symposium on Biochemistry of Membrane Transport was the first Symposium sponsored by the FEBS outside the yearly FEBS-Meetings, after the Special Meeting on Industrial Biochemistry, which took place in Dublin in 1973, and it reflects the interest and the trend for gatherings of smaller size than the official FEBS Meetings. The topic of the Symposium was an easy choice, not only because membrane transport is becom ing more and more important to biochemistry every year, but also because of the long-standing interest of Swiss Science in the field. In the choice of the topics and of the speakers, efforts were made to achieve as balanced a coverage of the area as possible. However, since some aspects of membrane biochemistry were dealt with extensively at the parallel 10th Inter national Congress of Biochemistry in Hamburg, GFR, cer tain topics were given less emphasis than others. The Symposium was attended by about 400 participants (we expected 200-250); among them 48 were invited speakers, and some 200 contributed posters."

This manual collects in the form of laboratory protocols a series of experiments in the field of Membrane Transport and Membrane Bioenergetics. It represents the experience accumulated during four advanced courses held at the Depart ment of Biochemistry of the Swiss Federal Institute of Technology on behalf of Federation of European Biochemical Societies (FEBS) in the years 1975 through 1978. The idea of collecting the experiments into a laboratory manual developed as a response to a demand from the students who took part in the courses. Further motivation came with the fmding that, in planning the laboratory sessions, the teaching staff had no organized, modern source of information in the literature. The experiments presented cover most areas of importance in the subject mat ter. Their presentation has been continuously modified in the course of the four years during which the manual took shape, to accommodate to experience and various suggestions. In their present form, all of the experiments described have been repeatedly practiced to optimize their execution. Efforts have been made to combine in the manual classical experiments, and techniques which require relatively unsophisticated instrumentation and can therefore be carried out in most laboratories, with more modern experiments and relatively newer technol ogies. In its present form, the manual should therefore provide a usefui tool in the hands of researchers and laboratory teachers at different levels of sophisti cation and instrumentation."
