Genome editing and generation of transgenic animals


Genetically modified organisms are crucial tools for life science research and beyond. The availability of knockout mice has transformed our understanding of the disease mechanisms of many disorders including cancer, obesity, and heart disease. Today, novel genome editing technologies, such as CRISPR-Cas9, open up a wealth of options for understanding genetic aberrations, the etiology of human disease and studying potential therapeutic targets.



Pronuclear injection is the most commonly used method for generating transgenic animals. Efficient and effective microinjection is critical for successful injection. Due to its exceptional performance and innovative operation concept, the Eppendorf micromanipulation system is ideal for the precise manipulation required for pronuclear injection. In this regard it is an excellent tool for making your work simpler and more reliable, when using CRISPR.
