3.3. Electron Microscopy
Electron microscopy has been used to study the size, shape, and structure of both the intact mucins and their subunits (9) . In addition, it can be used to identify the presence of specific epitopes or structural domains (10) . Two m[r]

1. Introduction
Progress in understanding how mucosal surfaces are protected is closely related to the development of morphologic techniques to study the structure and secretory func- tion of the mucosal epithelia. Morphologic methods have allowed characterization of mucus-secreting cells o[r]
