Background Information

Alpha Synuclein (α-syn) is a 14-19 kDa phosphoprotein that is primarily localize to the presynaptic terminals of mature neurons, where it is involved in synaptic function and plasticity. α-syn has drawn intense interest ever since the late 1990s, when the first α-synuclein missense mutation was identified as a cause of familial Parkinson's disease (PD). Aggregated and hyper-phosphorylated forms of α-syn protein are the pathological hallmark of Lewy body disease, which includes Parkinson's disease (PD), diffuse Lewy body disease (DLBD), and Lewy body variant of Alzheimer's disease (LBV). This antibody can recognize all the isoforms of α-syn.

Janelle (Verified Customer) (09-12-2022)

Perfect for WB!

  • Applications: Western Blot
  • Primary Antibody Dilution: 1:1000

BISHR (Verified Customer) (05-10-2022)

I used it in WB with 1:1000 ration, the band was clear and almost perfect. However, it says the expected kd ranges from 14 to 18, unfortunately I am getting far higher bands up to 50 kd sometimes. Although I am using concentrated acrylamide in the gel, it is making it difficult for reviewers to understand that.
