-beta-Amyloid (1-42), iowa mutation

[Asn23]-beta-Amyloid (1-42), iowa mutation is a biological active peptide. (Several mutations in the beta amyloid precursor gene cause autosomal dominant Alzheimer's Disease in a number of kindreds. The Iowa mutation, where Asp 23 is replaced with Asn, is associated with severe cerebral amyloid beta-protein angiopathy (CAA). The affected individuals share a missense mutation in APP at position 694. The mutated beta-amyloid peptide aggregates more rapidly and forms toxic fibrils.)
