N15 Beta-Amyloid (1-40), Uniformly Labeled
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 and isotope labeled in E. coli, Beta-Amyloid (1-40) is purified to our highest standards to ensure batch to batch consistency in both purity and quality.
Applications: The N15 isotopically labeled Aβ (1-40) could be used for NMR structural studies, as a molecular weight standard, a biomarker, and more.
