Abstract
A gene is transferred to the early stage chicken embryo by electroporation with placing the electrode tips to hold both ends of the embryo. Transfer of the desired gene to the early stage embryo was detected using the &bgr;-galactosidase gene of as a reporter gene. The expression of the gene in the early stage embryo of chicken was thus confirmed. This method for transferring a gene into undifferentiated cells is simple to implement, highly efficient in transferring a gene, and applicable to various animal species.
