Congo Red 78-80 amyloid beta precursor protein Homo sapiens 84-89 15709480-4 2005 As revealed by atomic models of the Abeta protofilament, such as the nanotube beta-helix and parallel beta-sheet, the regular arrangement of histidines likely acts as a template for the end-to-end J-aggregation of CR molecules, which produces a red shift in UV/V is absorption.
