Fig. 7. Hox2.4 is induced following treatment with retinoic acid. Blastula or gastrula stage embryos were treated with retinoic acid for 30 minutes. RNA was harvested at the neurula stage. Levels of neural induction were measured using an N-CAM probe. The full-length Hox 2.4 protection fragment is indicated. A lower level of induction was observed in embryos treated at the blastula as opposed to gastrula stage. The experiment shown in the figure was done using M RA. However, a similar result was seen with M RA. Each lane contained RNA from two embryos. The asterisks indicate degradation products from the Hox 2.4 ('1) and N-CAM ('2) probes.
