Ultrastructural localization of complex carbohydrates present in the sublingual gland of rabbits.
Stainings with dialized iron (DI), high-iron diamine-thiocarbohydrazide-silver proteinate HID-TCH-SP), tannic acid-uranylacetate (TA-U), tannic acid-ferric chloride (TA-F), and periodate-thiocarbohydrazide-silver proteinate (PA-TCH-SP) were applied to samples of sublingual glands of rabbits. Comparing the results obtained with what had been previously demonstrated biochemically, it is possible to assert that the faintly electron-opaque, granules of the cells of the preterminal tracts contain sulphated glycoconjugates because of the presence of sulphated hexosamines and hexoses, acid glycoconjugates because of the presence of sialic acid and uronic acids, and neutral glycoconjugates because of the presence of hexoses.
