Modular Advanced Practical

Heterologous Expression of Neurotransmitter Receptors in Frog Oocytes

In this course, the strategies and techniques necessary for studying structure-function relationships on recombinant neurotransmitter receptors and other ion channels are demonstrated using glutamate receptors as an example. Molecular biological, electrophysiological and protein biochemical techniques are utilized, which illustrates that a great variety of methods is required for solving modern questions in neurobiochemistry. This semester only the electrophysiology part will be offered.

The course is offered three times in the winter term 2021/2022.
