Yes, we are waiting on a new batch of GFAP, however it was our
understaning that in tissue it stains primarily activated astrocytes.  (Am
I wrong about that?)  We are trying to find an antibody that will stain
both activated and non-activated astrocytes in tissue sections.  We have a
reaction product from another histochemical stain that we are trying to
co-localize.  The first reaction is staining nuclei throughout the cortex,
and we are trying to find out if the nuclei are from neurons or
astrocytes.  We have tried S100-beta, but as it results in nuclear
staining as well, it's a bit problematic.

Thanks, 

Angie
