Analysis of transfer of microinjected zygotes in production of transgenic mice

Analysis of transfer of microinjected zygotes in production of transgenic mice The data on transfer of mouse eggs microinjected with DNA during production of transgenic mice were analyzed. The transfer of mouse eggs into both oviducts did not lead to a reliably higher birth rate. It did not affect the frequency of recipients’ pregnancy and, although somewhat increased the frequency of multiple birth, led, finally, to unjustified loss of the major part of viable DNA-injected eggs. We recommend transferring no less than 15 microinjected eggs only in one oviduct of each recipient. The transfer into another oviduct is acceptable if the transfer into the first oviduct failed or its outcome is doubtful. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Developmental Biology Springer Journals

Abstract

The data on transfer of mouse eggs microinjected with DNA during production of transgenic mice were analyzed. The transfer of mouse eggs into both oviducts did not lead to a reliably higher birth rate. It did not affect the frequency of recipients’ pregnancy and, although somewhat increased the frequency of multiple birth, led, finally, to unjustified loss of the major part of viable DNA-injected eggs. We recommend transferring no less than 15 microinjected eggs only in one oviduct of each recipient. The transfer into another oviduct is acceptable if the transfer into the first oviduct failed or its outcome is doubtful.
