Abstract
An improved apparatus and procedures for starch-gel electrophoresis of proteins of wheat flour are described; highly reproducible separation of the protein components was achieved. By starch-gel electrophoresis it was shown that similar protein components occur in the extracts of wheat flour obtained with a variety of solvents; however, there were marked differences in the proportions of these components in various extracts. Several protein components were present in the fJ'actions separated by ion-exchange chromatography of' the proteins soluble in Bodium pyrophosphate and of those soluble in acetic acid; some fractions containeda number of similar protein components.
