Alpha Synuclein Antibody (pSer129) [J18]

Alpha Synuclein Antibody (pSer129) [J18] is a rabbit recombinant monoclonal antibody directed against Alpha Synuclein Antibody (pSer129), offered by Assay Genie for research applications. Reported applications include ELISA, WB, ICC and IHC. Reported reactivity: Human and Mouse. Supplied as IgG, purified by Affinity.

Alpha-synuclein (SNCA) is a neuronal protein predominantly expressed in the brain, where it is enriched at presynaptic terminals and plays a key role in synaptic function (1). It is also highly expressed in mitochondria-rich regions such as the olfactory bulb, hippocampus, striatum, and thalamus, suggesting a role in mitochondrial dynamics and neuronal energy metabolism (2). Functionally, alpha-synuclein interacts with tubulin (3), indicating a potential role as a microtubule-associated protein involved in cytoskeletal organization and intracellular transport. It is essential for cognitive development, with SNCA inactivation linked to impaired spatial learning and working memory (4). Pathologically, SNCA aggregates are a major non-Aβ component of amyloid plaques in Alzheimer’s disease and a defining feature of Lewy body inclusions in Parkinson’s disease (PD). PD is characterized by the progressive accumulation of alpha-synuclein and ubiquitin-positive inclusions in vulnerable neurons, contributing to neurodegeneration (5, 6). Critically, phosphorylation of alpha-synuclein at serine 129 (pSer129) is a key post-translational modification associated with disease pathology. Approximately 90% of alpha-synuclein found in Lewy bodies is phosphorylated at Ser129, compared to only a small fraction in the healthy brain (7, 8). This modification is widely used as a biomarker for pathological alpha-synuclein and is a focal point in therapeutic and diagnostic research targeting synucleinopathies. This antibody is also available conjugated to ATTO 390, ATTO 488, ATTO 594, APC, Biotin, FITC, HRP, PerCP and RPE. Supplied in 100 µg. For research use only; not for diagnostic or therapeutic procedures.
