Purpose of Study

• To perform gene transfer into older chicken embryos in vivo.
• To investigate gene function and regulation at advanced developmental stages.
• To demonstrate the efficacy of X ovo electroporation.

Methods Used

• Cracking the egg at incubation day 2.5.
• Transferring the embryo into a Petri dish system.
• Injecting plasmid encoding the gene of interest into the embryo.
• Performing X ovo electroporation using electrodes.

Main Results

• Successful gene transfer into older chicken embryos.
• Detection of gene expression through immunohistochemistry.
• Demonstration of the X ovo electroporation technique.
