Protocol for in vivo analysis of pre- and post-synaptic protein function in mice.

ABSTRACT

Studying synapses in vivo presents challenges due to the complexity of accurately targeting and visualizing specific synaptic proteins within the brain. Here, we present a protocol for in vivo analysis of pre- and post-synaptic protein function in mice. We describe steps for combining adeno-associated virus (AAV)-mediated gene transfer to manipulate specific neuron subtypes. We also describe immunofluorescence on artificial cerebrospinal fluid (ACSF)-perfused brain sections to enhance the visualization of synaptic proteins. For complete details on the use and execution of this protocol, please refer to Cramer et al.1.
