Scientific Data Images for alpha-Synuclein Antibody

Immunohistochemistry: alpha-Synuclein Antibody [NBP2-25146]

Immunohistochemistry: alpha-Synuclein Antibody [NBP2-25146]

Immunohistochemistry: alpha-Synuclein Antibody [NBP2-25146] - Immunofluorescent analysis of a section of rat cerebellum stained with chicken pAb to alpha-synuclein, NBP2-25146, dilution 1:3,000 in red, and costained with rabbit pAb to 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 45uM, and free-floating sections were stained with above antibodies. The alpha-synuclein protein is concentrated in presynaptic regions in the granular and molecular layers, while GFAP antibody stains the network of Bergmann and astroglial cells.
Western Blot: alpha-Synuclein Antibody [NBP2-25146]

Western Blot: alpha-Synuclein Antibody [NBP2-25146]

Western Blot: alpha-Synuclein Antibody [NBP2-25146] - Western blot analysis of different tissue lysates using chicken pAb to alpha-synuclein, NBP2-25146, dilution 1:2,000 in green: [1] protein standard (red), [2] rat brain, [3] rat spinal cord, [4] mouse brain, [5] mouse spinal cord. The strong band at about 15kDa corresponds to the alpha-synuclein protein in brain extracts, which are rich in synapses, while a weaker band is seen in spinal cord extracts where synapses are a more minor component.
Immunocytochemistry/ Immunofluorescence: alpha-Synuclein Antibody [NBP2-25146]

Immunocytochemistry/ Immunofluorescence: alpha-Synuclein Antibody [NBP2-25146]

Immunocytochemistry/Immunofluorescence: Synuclein-alpha Antibody [NBP2-25146] - Mixed rat neuron-glial cultures stained with NBP2-25146, polyclonal antibody to alpha-Synuclein (red) and monoclonal antibody to MAP2 (NBP2-25156, green). The alpha-Synuclein antibody stains vesicular structures, the perikarya and processes of the neurons in this image. Note that some of the neuronal perikarya contain much more alpha-Synuclein than others. The blue channel shows the localization of DNA.

Background: alpha-Synuclein

Alpha-synuclein, a member of the synuclein family, is a protein that was first identified in 1988 whose name is derived from its localization to both the synapse and nucleus (1-3). Specifically, it is expressed primarily in the brain, including Lewy Bodies (1-6). Alpha-synuclein is encoded by the SNCA gene, located on chromosome 4p21, and is processed as a 140 amino acid (aa) protein with a theoretical molecular weight of 14 kDa (1,2,4). Structurally alpha-synuclein consists of a N-terminal binding domain (1-60 aa), a central domain core region called the non-amyloid-beta component (NAC) (61-95 aa), and a C-terminal domain (96-140 aa) (1-3). The N-terminal region contains aa repeats with a KTKEGV consensus sequence that gives the protein its alpha-helical structure that associates with lipid membranes (1-4). The hydrophobic NAC region is responsible for alpha-synuclein aggregation and fibril formation (1-4). The acidic C-terminal tail is largely unstructured but can be targeted for post-translational modifications (1-4). The function of alpha-synuclein is not entirely understood, but it is shown to have a role in suppression of apoptosis, acting as a molecular chaperone, regulating glucose, and modulating calmodulin activity (1,3).

A number of studies have revealed that alpha-synuclein aggregation is a hallmark feature in a number of neurodegenerative diseases, referred to as synucleinopathies (2-4). Alpha-synuclein protein aggregates are a large component of Lewy bodies that are present in Parkinson's disease (PD), Lewy body dementia (LBD), and multiple system atrophy (1-6). Research has shown phosphorylation of alpha-synuclein at Ser129 moves the protein from the nucleus to the cytoplasm and promotes fibril formation associated with synucleinopathies (1,2,5). Recent studies also suggest that alpha-synuclein accumulation can prevent mitochondrial import machinery causing mitochondrial dysfunction that is often observed in neurodegeneration (5). It is thought that preventing alpha-synuclein aggregation may prevent PD, thus alpha-synuclein is a target for many potential therapeutic interventions aimed at decreasing aggregate formation or increasing clearance (1,2,4-6).
