Re: Alkaline Phosphatase for meningiomas-HELP!

From:"L. Muffley"

we also had trouble staining 'neuro stuff'
specifically PGP9.5 in zinc fixed tissue
using Alk Phos Vector red substrate.
It's not the tissue and not our marker thats the problem,
but the vector red substrate.
We ended up using DAB - and had to contend with high background
because you cant block endogenous peroxidase in the zinc fixed
paraffin embedded tissue.

A Fluorescent marker might be a good bet for you.

Good luck-
