Zebrafish Microinjection Techniques
Description
One of the major advantages to working with zebrafish (Danio rerio) is that their genetics can be easily manipulated by microinjection of early stage embryos. Using this technique, solutions containing genetic material or knockdown constructs are delivered into the blastomeres: the embryonic cells sitting atop the yolk of the newly fert...

Transcript
Microinjection of zebrafish embryos allows researchers to deliver solutions directly into the developing animal, in order to study gene function and developmental dynamics. Embryos from the 1 to 4-cell stage are frequently used for injection. Because there are no membranes separating the cells and the yolk at this early stage...
