    摘要: The present invention provides cell-free &ggr;-secretase activity. The method of the invention utilizes a membrane source of APP/&ggr;-secretase mixture in the assay to determine factors that may enhance or decrease enzymatic activity affecting &bgr;-amyloid peptide production. The cell membranes used in the assay may be from cells expressing an endogenous APP or, preferably, cells expressing a recombinant APP. The APP may be full-length or a fragment capable of being proteolytically cleaved by &ggr;-secretase. In addition, the APP expressed in the cells may have one or more mutation, such as a point mutation, small deletion, etc.

    摘要: DNA sequences encoding the beta-amyloid core protein, and beta-amyloid-related proteins associated with Alzheimer's disease are disclosed. These sequences are used in producing or constructing recombinant beta-amyloid core protein, beta-amyloid-related proteins and recombinant or synthetic immunogenic peptides. These sequences are also used to identify genomic mutations and/or restriction site alterations which are associated with a predisposition to Alzheimer's disease, for purposes of genetic screening. Antibodies generated against the recombinant proteins or immunogenic peptides derived therefrom can be used for cerebral fluid or serum protein diagnosis of Alzheimer's disease.
