the ultrastructural distribution of complex carbohydrates in an early formation stage of rat incisor enamel was investigated by staining with the periodic acid-thiocarbohydrazide-silver proteinate reaction ( pa-tch-sp ) for vicinal glycol-containing glycoconjugates , the phosphotungstic acid-chromic acid mixture ( pta ) for glycoproteins , and the cationic dyes alcian blue or bismuth nitrate for sulfated glycoconjugates .
