Abstract: The present invention relates to novel uses for a family of small molecules, Differentiation-Inducing Factors (DIFs). It has been discovered that DIFs surprisingly can alter the metabolic processing of amyloid precursor protein (APP) and in turn reduce the level of secreted A?. The metabolic processing of other ?-secretase substrates normally present in cells (Notch and APLP1) is not affected when treated with DIF. The invention provides methods for reducing A? production in mammalian cells that express APP by administering DIF-I, DIF-2, DIF-3, a functionally equivalent analog and or any combination thereof. The invention also provides methods for treating and/or preventing Alzheimer's disease by preferentially reducing A? production.

Abstract: The disclosed invention relates to assays for detecting and quantifying A? peptide, using solid supports that are coated with heavy metal cations, such as zinc (II) or copper (II) form of a nitriloacetic acid. Further, diagnostic kits are described which are used to carry out the assays of the present invention. An improvement in an assay for detection of A? peptide is suggested which comprises forming a heavy metal cation/solid support complex. The preferred heavy metal cations for this improvement are zinc (II) or copper (II) form of a nitriloacetic acid. Finally, methods and kits for bulk purification of A? peptides from biological fluids are taught.
