... cysteine-rich part.Further localization of the epitopes of 45M1,2-12 M1 and 166M1In order to further locate the epitopes of the hithertounmapped 45M1, 2-12M1 and 166M1, these mAbswere screened ... of the C-terminal cysteine-rich part of MUC5AC, pre-sumably in the last CysD domain of the mucin. The epitope of 2-12M1 is located in the sequence corre-sponding to the expression product of ... domains. The C-terminal region of the protein is expanded, and its domains and GDPH-cleavage site are indicated. In the lower part of the figure, the mapped regions for the 45M1, 166M1 and 2-12M1 epitopes...
