Mouse Monoclonal Antibody to α-Synuclein Cat# MCA-2A7

$120.00 – $800.00

α-synuclein is a member of the synuclein protein family, the other two members being β and γ synuclein, each protein being coded for by a distinct but related gene. α-synuclein was originally isolated as a major synaptic vesicle associated protein from the electric organ of the fish Torpedo (1), and direct homologues of α-synuclein are found in all vertebrates. Later work connected α-synuclein expression with several human brain pathologies, so that it is a major component of the Lewy bodies of Parkinson’s disease (2). Point mutations of α-synuclein proved to be causative of some forms of familial Parkinson’s disease (3-5). One genetic cause of early onset Parkinson’s disease is duplication or triplication of one of the α-synuclein genes leading to excess production of the protein (6,7). α-synuclein is also found in the Lewy bodies of patients with diffuse Lewy body disease and inclusions in glial cells in the brains of patients with multiple system atrophy and amyotrophic lateral sclerosis. α-synuclein is normally heavily expressed in brain and appears to be localized primarily to presynaptic regions, though not with a typical synaptic vesicle distribution pattern.The MCA-2A7 antibody was made against full length recombinant human α-synuclein, EnCor product PROT-r-SNCA, and recognizes full length human and rodent α-synuclein specifically both in western blots and in immunocytochemical experiments. The epitope for MCA-2A7 is in the region 61-95 which correspond to the “Non-amyloid beta component of Alzheimer’s disease amyloid” (NAC, see above, also see http://encorbio.com/Album/pages/Synuclein-dots.html). As expected, MCA-2A7 will also bind human α-synuclein containing either the A30P or the A53T Parkinson’s associated mutations. The antibody has also been used as a capture reagent capable of detecting endogenous α-synuclein in human plasma (8). We also supple a chicken polyclonal antibody made against the same immunogen, CPCA-SNCA. Mouse select image at left for larger view.

α-synuclein is a member of the synuclein protein family, the other two members being β and γ synuclein, each protein being coded for by a distinct but related gene. α-synuclein was originally isolated as a major synaptic vesicle associated protein from the electric organ of the fish Torpedo(1), and direct homologues of α-synuclein are found in all vertebrates. Later work connected α-synuclein expression with several human brain pathologies. For example a protein originally identified as a component of NAC, the “Non-Amyloid beta Component of Alzheimer’s disease amyloid” proved to be a peptide derived from α-synuclein (2). α-synuclein protein is therefore sometimes known as NAC precursor or NACP. Further work showed that α-synuclein is a major component of the Lewy bodies of Parkinson’s disease and point mutations of α-synuclein proved to be causative of some forms of familial Parkinson’s disease (3-5). However, despite being discovered as as component of amyloid preparations, α-synuclein is apparently not a major component of the senile plaques of Alzheimer’s disease. One genetic cause of early onset Parkinson’s disease is duplication or triplication of one of the α-synuclein genes leading to excess production of the protein (6,7). α-synuclein is also found in the Lewy bodies of patients with diffuse Lewy body disease and inclusions in glial cells in the brains of patients with multiple system atrophy and amyotrophic lateral sclerosis. α-synuclein is heavily expressed in brain and appears to be localized primarily to presynaptic regions, though not with a typical synaptic vesicle distribution pattern. The synuclein proteins appear to have little 3D structure in solution, and so belong to the family of “intrinsically unstructured proteins” which only adopt a well-defined conformation when bound to other proteins or membrane lipids (see additional information tab). The MCA-2A7 antibody has also been used as a capture reagent in ELISA on human blood samples (8).

MCA-2A7 recognizes full length human and rodent α-synuclein specifically both in western blots and in immunocytochemical experiments. The epitope for MCA-2A7 is in the region 61-95 which correspond to the “Non-Amyloid beta Component of Alzheimer’s disease amyloid” (NAC, see above, also see here). MCA-2A7 will also bind human α-synuclein containing the A30P and A53T mutations. The antibody has also been used as a capture reagent capable of detecting endogenous α-synuclein in human plasma (see additional information tab).

Cortex of a patient with Parkinson’s disease (PD) stained with MCA-2A7, 1:1,000 dilution. Antibody revealed with horse radish peroxidase and DAB. The Lewy bodies and other typical inclusions of PD are seen in brown. Mouse select image for larger view.

Immunofluorescent analysis of rat hippocampus section costained with mouse mAb to α-synuclein MCA-2A7, dilution 1:1,000, in green, and chicken pAb to MeCP2 CPCA-MeCP2, dilution 1:2,000 in red). The blue is DAPI staining of nuclear DNA. Following transcardial perfusion of rat with 4% paraformaldehyde, brain was post fixed for 1 hour, cut to 45 μM, and free-floating sections were stained with above antibodies. The α-synuclein protein is concentrated in synaptic regions, and the MeCP2 antibody stains the nuclei of neuronal cells. Mouse select image for larger view.

Immunofluorescent analysis of rat olfactory bulb section costained with mouse mAb to a-synuclein MCA-2A7, dilution 1:1,000 in red, and rabbit pAb to GFAP RPCA-GFAP, dilution 1:5,000 in green. The blue is DAPI staining of nuclear DNA. Following transcardial perfusion of rat with 4% paraformaldehyde, brain was post fixed for 24 hours, cut to 45μM, and free floating sections were stained with above antibodies. The α-synuclein protein is concentrated in synaptic regions, while the GFAP antibody stains the filamentous backbone of astroglial cells. Mouse select image for larger view.

Various trancated and mutant construct were applied to PVDF membranes in about of 400ng of each protein. These were the first 60 amino acids of human https://encorbio.com/product/mca-2a7/alpha-synuclein (1-60), amino acids 61 to 140 (61-140), full length but incorporating the A30P and A53T mutations seen associated with familial forms of Parkinson’s disease (A30P/A53T), full length but with the central NAC region of amino acids 61-95 missing (d61-95) and finally full length alpha synuclein. The strips of PVDF were probed with MCA-2A7, MCA-3H9, the Santa Cruz monoclonal antibody 211, the Santa Cruz rabbit polyclonal (R-SC) and EnCor’s rabbit polyclonal (R-EnCor, RPCA-aSyn). The epitopes for MCA-2A7 and MCA-3H9 are clearly in the NAC region from 61-95, while the 211 antibody epitope is within the C-terminal region from 95-140 (in fact the epitope has been shown to be aminoacids 120-125). Both rabbit antibodies bind constructs including amino acids 61-140, but do not appear to bind amino acids 1-60, suggesting that this region has low immunogenicity.
