[Histonet] detect primordial germ cells in PFA-fixed marsupial embryos...?

From:Bruce Abaloz

I have been using alkaline phosphatase histochemistry to detect 
primordial germ cells in PFA-fixed marsupial embryos. I use 1mg/ml 
Fast Blue salt and 1mg/ml Naphthol AS phosphate sodium salt in 0.2M 
Tris buffer, pH 9.4. The staining is good but I have been told that 
it is not permanent. Ideally, I would like to dehydrate these stained 
specimens, embed them in paraffin and then section and stain them 
immunohistochemically for other germ cell markers and several growth 
factors. Does anyone have a protocol utilising alkaline phosphatase 
histochemistry that would allow me to do this? Thanks for any advice 
in advance,
