Hi Netters,


I'm stumped with a project and could really use your help. I have 3mm
punches of skin that I need to stain with PGP 9.5 but I am specifically
looking for the intraepidermal nerve fibers.  The sections were given to
me fixed in formalin and then I made cryo buttons out of them using OCT.
I have found various articles that have cut sections ranging from 4
microns on up to 50 microns. I cut a slide to try at 20 microns but need
help after this.  I am using a polymer based detection system and the
antibody is polyclonal from Dako.  I know the antibody works well on
paraffin embedded tissue but I'm lost with a starting point for these
frozen 20um sections.  Some journal articles also have the primary
incubating overnight. Is this the only way I will be able to see the
IENF's? If anyone out there is doing this kind of work can you please
contact me. Thank you in advance.
