Das Zebrafish Tol2-System: Ein modularer und flexibler Gateway-basierter Transgenese-Ansatz

Overview

This work describes a protocol for the modular Tol2 transgenesis system, a gateway-based cloning method to create and inject transgenic constructs into zebrafish embryos. The Tol2 system is a versatile tool that enables researchers to quickly and systematically generate multiple transgenic zebrafish for FASD studies.
