This video describes the technique of intramuscular injection for delivering compounds into the dorsal muscles of an adult zebrafish.
Protocol
1. Injection of the DNA Vaccine and Electroporation For immunizations according to this protocol, use healthy, 6 to 12 month-old adult zebrafish. Keep the fish in a flow-through system with a 14/10 h light/dark cycle, with a maximum of seven fish per 1 L of water. Prepare a 0.02% 3-aminobenzoic acid ethyl ester (tricaine) solution (pH 7) in tank water for anesthetizing the fish. Use a 10 cm Petri dish or something similar. Prepare a recovery tank by filling a 5 L beaker with 3 L of clean s…
