1. The neurosecretory system of the primitive ellobiid Melampus bidentatus (Pulmonata: Basommatophora) was investigated using Alcian blue-Alcian yellow histochemistry. 2. Putative neurosecretory cells within the central ganglia were distinguished by the criteria of cell size, position, and staining reaction. 3.

The isolation and characterization of mucins are critically important for obtaining insight into the molecular pathology of various diseases, including cancers and cystic fibrosis. Recently, we developed a novel membrane electrophoretic method, supported molecular matrix electrophoresis (SMME), which separates mucins

Alcian blue and toluidine blue dyes form complexes with anionic glycoconjugates (AG) such as proteoglycans (PG) and glycosaminoglycans (GAG). However, the Alcian blue-AG complexes do not readily dissociate, while the toluidine blue-AG complexes do so in salt solutions. This differential
