Germ line transformation of mammals by pronuclear microinjection.
The most popular approach for generating transgenic mammals is the direct injection of transgenes into one pronucleus of a fertilized oocyte. In the past 15 years microinjection has been successfully applied in laboratory as well as in farm animals. The frequency of transgenic founders, although highly different between the species, is efficient enough to render this technique applicable to a w...
متن کاملPronuclear Microinjection of Rabbit Fertilized Eggs
Although, the first transgenic animal was produced more than 30 years ago, there are still many factors limiting efficiency of transgenesis. One of them is the low rate of transgene incorporation into the genome of microinjected eggs. This mini-review summarizes recent research methods based on pronuclear microinjection of rabbit fertilized eggs in order to reach higher efficiency of transgene ...
متن کاملReview Production of functional transgenic mice by DNA pronuclear microinjection
Successful experiments involving the production of transgenic mice by pronuclear microinjection are currently limited by low efficiency of random transgene integration into the mouse genome. Furthermore, not all transgenic mice express integrated transgenes, or in other words are effective as functional transgenic mice expressing the desired product of the transgene, thus allowing accomplishmen...

متن کاملHyperactive self-inactivating piggyBac for transposase-enhanced pronuclear microinjection transgenesis.
We have developed a unique method for mouse transgenesis. The transposase-enhanced pronuclear microinjection (PNI) technique described herein uses the hyperactive piggyBac transposase to insert a large transgene into the mouse genome. This procedure increased transgene integration efficiency by fivefold compared with conventional PNI or intracytoplasmic sperm injection-mediated transgenesis. Ou...
