Lectin-gold complexes in the dark granules (DGs) and the dense substance (DS) of vallate taste buds were localized. Both the DGs and the DS were labelled with wheat-germ agglutinin, Ulex europeus agglutinin-I and peanut agglutinin. Their common reaction to these lectins suggested that the DGs contain carbohydrate components similar to those of the DS. The results provide cytochemical evidence that the DS in the taste pit represents, at least in part, the content of the DGs in the type 1 cells.
