In the zebrafish regenerating fin, specific gene-targeting morpholinos have been widely utilized to assess gene function. Unlike in embryos, injection of standard morpholinos in the adult regenerating fin is not sufficient for cellular uptake. Rather, morpholinos are first injected extracellularly into the blastemal compartment, followed by electroporation for cellular uptake. Knockdown phenotypes are evaluated 1–4 days post electroporation. This chapter provides a description of the reagents, equipment, and procedure for successful injection and electroporation of morpholinos into the regenerating fin.
