What is lentiviral transgenesis?
Lentiviral transgenesis is a method used to incorporate transgenes into the genome of an organism using lentiviral vectors.
Why are transgenic animals important?
Transgenic animals allow researchers to study gene function and the effects of genetic modifications in a living organism.
What strains of rats are used in this study?
Wistar female rats are used, mated with fertile males of a different dominant fur color.
What is the role of human chorionic gonadotropin in this process?
Human chorionic gonadotropin is administered to induce ovulation in female rats prior to mating.
How are the embryos prepared for transgenesis?
Embryos are harvested from the oviducts of females that have been mated and checked for vaginal plugs.
