title: Increased osmiophilia of glycosaminoglycan-like structures after fixation with cetylpyridinium chloride in human colonic mucosa.
abstract: The effects on tissue ultrastructural appearance of fixation with cetylpyridinium chloride (CPC)-additioned formaldehyde were studied at the ultrastructural level in human colonic mucosa. We found that CPC did not impair tissue morphology and induced a remarkable osmiophilia in glycosamino-glycan-like structures, which did not require further staining.
