Alpha synuclein (phospho Ser129) Antibody

Alpha-synuclein is a presynaptic neuronal protein that is thought to be involved in the formation of SNARE complexes. Most significantly, aggregated alpha-synuclein is one of the major components found in the Lewy bodies that occur in Parkinson’s disease (PD) and other neurodegenerative disorders (Okochi et al., 2000) . Mutation of the alpha-synuclein gene is associated with familial forms of PD (Newmann et al., 2002) . Recent evidence suggests that phosphorylation of alpha-synuclein at ser129 plays a role in the formation of inclusions in PD (Smith et al., 2005; Masliah et al., 2005) .

The antibody has been directly tested for reactivity in Western blots with rat tissue. It is anticipated that the antibody will react with bovine, canine, human, mouse, and non-human primate based on the fact that these species have 100% homology with the amino acid sequence used as antigen.
