A microspectrophotometric study of the periodic acid-Schiff reaction product in the rat central nervous system.
The comparison of microspectrophotometric curves recorded from PAS-stained brain slices reveals clear-cut differences concerning the fixation method and the age of the animal, namely the colour is weaker in Carnoy-fixed tissue and in perinatal rats as referred to Bouin mixture and adult animals, respectively. It seems that the PAS-positive reaction in the rat brain is mainly due to glycolipids rather than to complex polysaccharides.
