(ALPHA)-Synuclein Aggregation Assay Kit

α-Synuclein Aggregation Assay Kit mimics intracellular aggregation of "α-Synuclein" seen in Lewy Body Dementia / Parkinson Disease / Multiple system atrophy.
Cell aggregation inhibition and/or preventive effects of your cell culture assay can be tested with this kit.

α-Synuclein Aggregation Assay KitDementia is a disease that causes memory and judgement loss, there is no fundamental treatment developed for it. Years of scientific research has proven that protein aggregation occurs in the degeneration part of the brain for many neurodegenerative diseases including dementia, indicating appearance of this aggregation is closely related to these diseases development and progression.

Aggregation occurs when normal protein forms abnormal structure for particular reasons and accumulates in the cell, which each disease has different aggregating protein. It is known that protein called "α-Synuclein" forms abnormal structure in Parkinson Disease / Lewy Body Dementia / Multiple system atrophy patient brain.

α-Synuclein Aggregation Assay Kit mimics intracellular aggregation of "α-Synuclein", which allows in vitro screening of active ingredients.

Overview of the assay flow



Detection example of α -Synuclein aggregation complex

1. Western blotting (Use of various synuclein antibodies)

  1. Remove culture medium.
  2. Add 1 mL PBS to each well, collect cells by pipetting.
  3. Centrifuge (4,500 rpm [1,800 x g], 5 min., room temp.), collect pellet.
  4. Add 0.1 mL Lysis Buff er (10 mM Tris-HCl, pH 7.5 containing 0.8 M NaCl, 1 mM ethyleneglycol bis(2-aminoethyl ether)-N,N,N,N-tetraacetic acid (EGTA), 1 mM DTT and 1% N-Lauroylsarcosine sodium salt ), sonicate mixture.
  5. Centrifuge (50,000 rpm [100,000 x g], 20 min., room temp.).
  6. Add 40 µL 2 x SDS Buffer (0.125 M Tris-HCl pH6.8, 200 mM 1,4 dithiothreitol (DTT), 4% sodium dodecyl sulfate(SDS) , 10% Sucrose, 0.01% BPB) to pellet, sonicate mixture, heat (100 °C,5 min), apply 10 µL/well for western blotting.

​Note: The accumulated synuclein ​inside cells was collected by ultra-centrifuge after homogenized with surfactant. Then, treat by SDS and sonication. This leads to denature of the accumulated synuclein, some turns to be monomers or smeared structures etc.



2. Amyloid structure fluorescent staining kit

By use of Amyloid Structure Fluorescent Staining Kit (Cosmo Bio, cat. no. CSR-SYN02-COS), dual staining of aggregated α-Synuclein and nucleolus can be performed.
