Protocol to visualize ion channel trafficking in acutely isolated rodent neurons using live-cell immunocytochemistry

Abstract

Summary: Here, we present a protocol for live-cell immunocytochemistry to demonstrate reversible translocation of ion channels to the neuronal cell surface. We describe steps for cell preparation and isolation, experimental treatment, antibody binding prior to fixation, specific pipetting techniques, troubleshooting, and expected outcomes of correct use of the protocol. This protocol will be useful to study regulated translocation of ion channels and other membrane proteins.For complete details on the use and execution of this protocol, please refer to Haan et al.1 : Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.
