Identification of a Unique Group of High Molecular Weight Proteins in Some Wheat Varieties.

A unique group of high molecular weight proteins, similar in mobility to the high molecular weight subunits of glutenin, was identified by sodium dodecyl sulfate-polyacrylamide gel electrophoresis in some Canadian wheat varieties. These proteins are extractable from flour or gluten with acetic acid and with acetic acid/urea solutions. They were not extracted with traditional solvents used for glutenin extraction that contain detergents such as cetyltrimethylammonium bromide or sodium dodecyl sulfate/2-mercaptoethanol.
