Re: [Histonet] embedding problem small zebrafish

From:"Andrea Hooper"

Have you checked out the histological methods section of "The Zebrafish Book" by Monte Westerfield, on available online here:
I don't think it has paraffin embedding protocols but perhaps there are some other hints will help? In any case, it's an amazing resource.

I am also wondering if it might help to embed in agarose before paraffin embedding - especially those 44 hour old critters who are tiny tiny tiny. Unfortunately most of my experience in that regard lies with frozen sectioning so I don't have too much to add.
