title: The influence of fixation on staining of glycosaminoglycans in glial cells.
abstract: Cytoplasmic staining of glial cells by Alcian blue in 0.40 M magnesium chloride can be demonstrated in sections of brain tissue fixed in formol-acetic acid and in Bouin's solution. Phosphate-buffered aldehyde fixatives, whether at neutral or low pH, fail to preserve stainable material.
