Rabbit antibody to alpha synuclein (129-140): whole serum

Alpha synuclein is an abundant 140 amino acid neuronal protein, expressed primarily at presynaptic terminals in the central nervous system. FUNCTION: May be involved in the regulation of dopamine release and transport. Soluble protein, normally localized primarily at the presynaptic region of axons, which can form filamentous aggregates that are the major non amyloid component of intracellular inclusions in several neurodegenerative diseases (synucleinopathies). Induces fibrillization of microtubule-associated protein tau. Reduces neuronal responsiveness to various apoptotic stimuli, leading to a decreased caspase 3 activation. TISSUE SPECIFICITY: Expressed principally in brain but is also expressed in low concentrations in all tissues examined except in liver. Concentrated in presynaptic nerve terminals.SUBUNIT: Soluble monomer which can form filamentous aggregates. Interacts with UCHL1. Interacts with phospholipase D and histones. SUBCELLULAR LOCATION: Cytoplasm. Membrane. Nucleus. Note=Membrane-bound in dopaminergic neurons. Also found in the nucleus. ALTERNATIVE PRODUCTS: 3 named isoforms produced by alternative splicing. Additional isoforms seem to exist.

After reconstitution keep aliquots at -20AC for a higher stability, and at 4AC with an appropriate antibacterial agent. Glycerol (1:1) may be added for an additional stability. Avoid repetitive freeze/thaw cycles.

Lyophilised

This antibody is known to react with human, mouse and rat alpha synuclein. Other species have not yet been tested.

Immunohistochemical and western blot analysis of human brain indicates a high level of specificity for this antiserum.
