  • Patent number: 7250551
    Abstract: Disclosed are improved methods of treating individuals with Alzheimer's disease (AD) as well as methods to diagnose AD in an individual. Also included are compounds and methods of identifying compounds to treat AD. The present invention also discloses methods for decreasing the phosphorylation of amyloid precursor protein (APP), including inhibiting phosphorylation of amino acid residue tyrosine 668 of APP and for reducing cleavage of APP. The present invention further discloses transgenic (Tg), non-human animals and cells expressing a p25 transgene that are models of neurodegenerative diseases. Embodiments of the present invention are directed to methods wherein the Tg animals and Tg cells of the invention are used to screen for modulators of neurodegenerative disorders.

  • Publication number: 20050261475
    Abstract: One aspect of the present invention relates to a method of labeling a peptide or protein comprising a phosphorylated amino acid comprising: a) removing from the peptide or protein the phosphate group via a ?-elimination to form a double bond conjugated to a C?O group; b) reacting the double bond from step a) with a nucleophile comprising a tag on a solid support; and c) removing the solid support from the product of step b) forming the labeled peptide or protein. A second aspect of the invention relates to a solid support comprising a linker and tag between the solid support and a nucleophile, wherein the tag comprises a label.
