Since we try to perform immunofluorescence with brain
tissue (cryosections) fixed with formaldehyde 
autofluorescence is always a problem - doesn't matter
which wavelength we use. I tested the treatment with
sodium borohydride but there is no difference to the
untreated sections.
Does anybody know a method how to reduce the fluorescent

Any hints are welcome,
