Beta-Amyloid (1-42) Preformed Fibrils
Product background: Beta-Amyloid peptides (A-beta), the major constituent of amyloid plaques in the brains of Alzheimer’s patients, is thought to be a primary contributor to Alzheimer’s Disease (AD).
About the product: Expressed recombinantly in E. coli, human Beta-Amyloid (1-42) is purified to our highest standards to ensure batch to batch consistency in both purity and quality. The human Beta-Amyloid is then made into preformed fibrils with their presence and length being confirmed by transmission electron microscopy (TEM) and thioflavin fluorescence assay.
Applications: These human Beta-Amyloid (1-42) fibrils are sold as a frozen 4mg/mL solution of total protein. The fibrils could be suitable for either in vitro or in vivo requirements such as fibril stability, seeding experiments, aggregation studies, or preformed fibril injections. Beta-Amyloid preformed fibrils may also be used as an amyloid plaque model in any other study of Alzheimer’s disease.
