WebbPressure injection is an especially useful alternative to electroionophoresis, since it does not mandate the use of charged ions. Two different positive pressures may be applied–one for ejection at high pressure and a second, lower pressure to prevent back filling of the pipette by capillary action. WebbThe injection pipette does not always penetrate the pronucleus perfectly, and leaking of DNA out of the pronucleus or out the side of the pipette at the injection site will frequently occur. In this case, the pronucleus will not expand as rapidly, and the whole egg will enlarge.
