Beta-Amyloid (1-40), HFIP
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 of Alzheimer’s Disease (AD).
About the product: Expressed recombinantly in E. coli, Beta-Amyloid (1-40) is purified to our highest standards to ensure batch to batch consistency in both purity and quality. This product if treated with HFIP (hexofluoro-isopropanol) and then dried, leaving a clear dry film, rather than a lyophilized powder.
Applications: The HFIP counter ion of our Aβ ensures a highly monomeric starting material that could be suited to aggregation studies, seeding experiments, molecular standards, and more.
