General description

ZooMAb antibodies represent an entirely new generation of recombinant monoclonal antibodies.

Each ZooMAb antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb antibodies are reliably available and ready to ship when you need them.

Target description

a-synuclein (UniProt: P37840; also known as Non-A beta component of AD amyloid, Non-A4 component of amyloid precursor, NACP) is encoded by the SNCA (also known as NACP; PARK1) gene (Gene ID: 6622) in human. a-synuclein is abundantly expressed in the brain and is found in a classic amyloid fibril form within the intra-neuronal Lewy body deposits of Parkinson′s disease brains. In its monomeric form it participates in synaptic vesicle exocytosis by enhancing vesicle priming, fusion and dilation of exocytotic fusion pores. It acts by increasing local Ca2+ release from microdomains which is essential for the enhancement of ATP-induced exocytosis. In its multimeric form it acts as a molecular chaperone assisting in the folding of synaptic fusion components called SNAREs at presynaptic membrane. It is also involved in the regulation of dopamine release and transport. It is also reported to reduce neuronal responsiveness to various apoptotic stimuli, leading to a decreased caspase-3 activation. Post-translationally it can be phosphorylated, predominantly on serine residues. Phosphorylation of serine 129 is reported to be selective and extensive in synucleinopathy lesions. Genetic alterations of SNCA gene is reported to result in aberrant polymerization into fibrils, which is associated with several neurodegenerative diseases (synucleinopathies). Mutations in SNCA gene are also known to Parkinson′s disease characterized by bradykinesia, resting tremor, muscular rigidity and postural instability. The pathology of Parkinson s disease involves progressive loss of dopaminergic neurons in the substantia nigra and the presence of Lewy bodies in surviving neurons in various areas of the brain. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Physical form
