Overview
This video demonstrates the technique of targeted retinal injection and in ovo electroporation of DNA/RNA constructs into the chick embryonic retina at Hamburger and Hamilton stage 22-23, approximately embryonic day 4 (E4). This method is valuable for studying gene expression, regulation, and morphological changes in the developing chick retina.
