| Abstract: | A histochemical study of the epidermal mucous cells of brown trout revealed that they contained both neutral and acidic mucosubstances which were diastase-resistant, PAS-reactive. Neuraminidase treatment, methylation and combined staining procedures suggested that the acidic nature of the mucins was due mainly to the presence of sialic-acid containing glycoprotein. These results augment data derived from biochemical analyses of the epidermal mucus of salmonid fish. |
