More Than One Disease Process in Chronic Sinusitis Based on Mucin Fragmentation Patterns and Amino Acid Analysis

Figure 2

Densitometric scans of SDS-PAGE of polymeric and fragmented MUC5AC and MUC2 rich sinus mucins. The -axis represents the localization of the different PAS-positive peaks relative to the site of application on the stacking gel (1) and the interface between the stacking and migration gel phases (2). The -axis represents the relative absorbance of the different PAS-positive material (mucins) measured in arbitrary units. For the purpose of comparison of the different electrophoretic patterns, the presented figures were arranged as follows: ((a), (c), (e), and (g)) polymeric, reduced, papain digested, and trypsin digested MUC5AC rich mucins, respectively; ((b), (d), and (f)) polymeric, reduced, and papain digested MUC2 rich mucins, respectively.
