Live imaging of microtubule dynamics at excitatory presynaptic boutons in primary hippocampal neurons and acute hippocampal slices.

Analyses of microtubule (MT) plus end dynamics at glutamatergic boutons can be carried out in cultured primary neurons isolated from mouse or rat embryos or in acute slices isolated from mice that had been electroporated . Here, we describe a protocol for setting up and analyzing live image recordings of primary neurons and acute hippocampal slices expressing tagged versions of the MT plus end binding protein EB3 and the presynaptic vesicle markers vGlut1 or VAMP2. For complete information on the use and execution of this protocol, please refer to Qu et al. (2019).
