Gene Sequence (IMAGE) Neural Regeneration Research Caption This is a gene sequence scanning image of the rat embryonic neural tissue at embryonic 10.5 days. Normal control group labeled with Cy3 markers (green); retinoic acid group labeled with Cy5 (red). If the Cy5 signal was stronger than the Cy3 signal, the two fluorescent signals were superimposed and stained red, otherwise they were stained green.
