Beta-Amyloid (1-42), NaOH
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 (1-42) is purified to our highest standards to ensure batch to batch consistency in both purity and quality.
Applications: The NaOH counter ion of our Aβ is lyophilized in a basic environment, which some consider to be more physiologically relevant and less toxic. It also ensures a highly monomeric starting material that could be suited to aggregation studies, seeding experiments, molecular standards, and more.
