Method of introducing exogenous genes into cultured cells or fertilized eggs

摘要

There is provided a method of introducing exogenous genes into cultured cells or fertilized eggs, characterized in that each exogenous gene is introduced into chromosomal DNA in a cultured cell or fertilized egg under a condition where the exogenous gene is placed between insulators so as to ensure an insulated environment, such that the introduced exogenous gene will not be affected by any influence from adjacent genes in the cultured cell or fertilized egg.
