Advanced Biophysics Laboratory Course
|Lecturer:||Joachim Heberle, Jacek Kozuch, Sabine Oldemeyer|
|max. number of participants||-|
10 ECTS only together with lecture 20114101.
At the beginning of the practical, you will be introduced into laser safety rules and chemistry lab regulations. Participation is mandatory. Without your participation, you are not allowed to enter the practical.
The advanced laboratory course in biophysics will contain selected spectroscopic techniques on relevant biomolecules like proteins and artificial membranes. Among others, the course will include stationary and time-resolved optical and vibrational spectroscopy of proteins, impedance spectroscopy and application of a quartz micro balance to artificial membranes as well as activity measurements of a molecular proton pump by the stopped-flow technique. Groups of two students each have to perform four experiments during this course. Evaluation of the experiments will be done in written form.
