Abstract

Procedures for the production of transgenic animals have low overall efficiency. To evaluate factors responsible for low efficiency, zygotes of two species, varying intensities of microscope light, different qualities of injection pipettes, and six different genes were tested for their influence on the efficiency of pronuclear gene injection for the production of transgenic rabbits and mice. Rabbit zygotes were less sensitive to mechanical manipulation during injection than mouse zygotes. Exposing zygotes to a microscope light intensity of 5550 lx significantly reduced their cleavage rate, while a lower intensity (2280 lx) did not. Using pipettes with a filament for pronuclear gene injection..
