Beta-Amyloid (1-38)
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, Beta-Amyloid (1-38) is purified to our highest standards to ensure batch-to-batch consistency in both purity and quality.
Applications: The TFA (trifluoroacetic acid) counter-ion ensures a highly monomeric starting material that may be suited to aggregation studies, seeding experiments, molecular standards and more.
