[Histonet] 2) Immunofluorescence and background

From:Cath Gorrie

I have a different but similar problem with Immunofluorescence and
background. I'm cutting rat spinal cord sections that have been perfused and
post fixed in 4% paraformaldehyde, cryoprotected and cut as frozen sections.

The autofluorescence in the tissue is so high I am unable to clearly see
fluorescent labelled cells.

Is this a problem of the fixation in 4% paraformaldehyde? or a property of
spinal cord? or is there something obvious I should or shouldn't be doing?

Regards, cath
