Merck, MABN389, Anti-Aggregated a-Synuclein Antibody, clone 5G4

α-Synuclein, also known as Non-A beta component of AD amyloid or Non-A4 component of amyloid, or NACP, and encoded by the gene SNCA/NACP/PARK1, is a protein originally identified as non-Abeta component protein (NACP) in the amyloid enriched fraction isolated from Alzheimer’s brain tissue. α-Synuclein is expressed in neural tissue and non-neural tissues too. In neurons, α-Synuclein is localized to the nucleus, presynaptic termini and mitochondria of certain brain regions. α-Synuclein is a molecular chaperone that binds various proteins and compounds including synaptobrevin-2 protein and membrane phospholipids and is involved in vesicle trafficking and membrane transport within neurons. Natural, non-mutated α-Synuclein has autoproteolytic activity and naturally forms stable alpha helical tetramers. However, mutated α-Synuclein can aggregate to form insoluble pathological complexes such as Lewy Bodies inside neurons. Lewy Bodies also contain ubiquitin and it is thought that they are evidence of disrupted proteasome function with regards to α-synuclein but research is still continuing.Pepscan epitope mapping experiments showed that the epitope of 5G4 seems to be hidden inside full-length a-synuclein in aqueous solution, and this fact could depend on a specific conformation of the molecule. Thus, after conformational change, like b-sheet building, the binding structure of 5G4 may be accessible in biological samples.This antibody can be used as a sandwich ELISA pair with Cat.
