Abstract
Amyloid fibrils are found in many diseases such as Alzheimer’s Disease, Parkinson’s Disease, Huntington’s Disease, Type 2 Diabetes, Rheumatoid Arthritis, and many more. These fibrils are protein aggregates with a characteristic β-sheet formation, which binds Congo Red. It is possible that the formation of amyloid deposits is “catalyzed” by solid liquid interfaces. In this experiment the rate and extent of aggregation of bovine insulin was determined in the presence of several different surfaces. The experiments were design to deepen our knowledge about the formation of amyloid deposits without which limited progress may be achieve in finding cures for these devastating diseases. The chemistry of surfaces was chosen to mimic those surfaces found in cells. The rate of aggregation was followed by dynamic light scattering, which was used to monitor the aggregate size as a function of time. Congo Red assays were performed to confirm if the aggregates were amyloidic.
