  • Publication number: 20190227082
    Abstract: The invention provides methods of detecting both total alpha-synuclein and S129 phosphorylated (pS129) alpha-synuclein using a donor complex, a first acceptor complex, and a second acceptor complex. The donor complex comprises an antibody that specifically binds to alpha-synuclein linked to a support and a donor label. The 4B12 antibody is an example of a suitable antibody in the donor complex. The first acceptor complex for detecting pS129 alpha-synuclein comprises an antibody that preferentially binds to pS129 alpha-synuclein linked to a support and a first acceptor label. The 11A5 antibody is an example of a suitable antibody in the first acceptor complex. The second acceptor complex for detecting alpha-synuclein comprises an antibody that binds to alpha-synuclein regardless of S129 phosphorylation. The LB509 antibody is an example of a suitable antibody in the second acceptor complex.

  • Patent number: 9879071
    Abstract: The application identifies novel fragments of alpha-synuclein in patients with Lewy Body Disease (LBD) and transgenic animal models thereof. These diseases are characterized by aggregations of alpha-synuclein. The fragments have a truncated C-terminus relative to full-length alpha-synuclein. Some fragments are characterized by a molecular weight of about 12 kDa as determined by SDS gel electrophoresis in tricine buffer and a truncation of at least ten contiguous amino acids from the C-terminus of natural alpha-synuclein. The site of cleavage preferably occurs after residue 117 and before residue 126 of natural alpha-synuclein. The identification of these novel fragments of alpha-synuclein has a number of application in for example, drug discovery, diagnostics, therapeutics, and transgenic animals.
