Hi Rhonda,
I recently had an investigator request this. We got the best results by 
staining the mouse embryos with Benzadine after fixation in Bouin's. I 
believe we stained them for 30 minutes in Benzadine. After staining, 
just process and cut like normal and you should see staining on the 
tissue. In addition to the Benzadine staining, we stained the slides 
with Okajima's and the investigator was very happy with the results.

I hope this helps,
