Abstract:
Two electrophoretic techniques have been developed for the analysis of synthetic beta-A4 related peptides. The first is an acetic acid--urea--polyacrylamide gel electrophoresis denaturing system while the second employs capillary zone electrophoresis at pH 7. Both methods were calibrated to identify the state (monomeric or aggregate) of the longer amyloid fragments beta-A4(1-40) and beta-A4(1-43) during analysis.
