Various sizes of materials may be present throughout the aggregation process, but small scatterers are difficult to detect in the presence of large ones. Fluorescence photobleaching recovery studies on 5-carboxyfluorescein-labeled Aβ1-40 peptide solutions readily confirmed the presence of large and small species simultaneously. The effects of dye substitution on the aggregation behavior of Aβ1-40 peptide are subtle, but should not prevent further investigations by fluorescence photobleaching recovery or other fluorescence methods.enBook chapter
