Description
Summary:A successful embryo transfer depends on the quality of the transferred embryos, recipients, and the transfer techniques. Among these, transfer techniques are often the limiting factor because transfer methodologies and personal skills vary. Suboptimal embryo transfer procedures can compromise transgenic experiments (pronuclear microinjection and gene targeting) and critical steps of mouse colony maintenance (embryo cryopreservation and mouse line rederivation). Here we present an efficient and simple procedure utilizing specific designs to improve the transfer quality. A 100% implantation rate is observed after the utero‐tubal embryo transfer, which indicates that the modified method successfully prevents the embryos from flowing out of the punctured hole during embryo transfer. We believe this alternative methodology is able to fulfill the need of high efficiency of animal production. genesis 30:77–81, 2001. © 2001 Wiley‐Liss, Inc.
