Dear Criss,
I would suggest fixing the coverslips in 95% ethanol (minimum 20min)
and then doing your IPX on them. Most antibodies work very well on
ethanol fixed material. There is no antigen retieval required (no formalin
or other cross-linking fixatives used). S100, though can be problematical.
The antigen is somewhat alcohol soluble, so in some cases a false
negative result will occur.
Hope this helps.
