Overview
Single-cell electroporation (SCE) is a technique that enables the delivery of DNA or macromolecules into individual cells within intact tissue, including in vivo settings. This article details the procedure for SCE of fluorescent dyes or plasmid DNA into neurons in the intact brain of the Xenopus laevis tadpole.
