Introduction
Alpha-synuclein (a-synuclein), a 140-amino acid neuronal protein, plays a role in Parkinson's disease and related neurodegenerative disorders. This protein exhibits heat resistance, an extended unfolded structure with random coils, and potential involvement in vesicular transport regulation. Studies indicate its chaperone activity, which is influenced by the C-terminal acidic tail (amino acids 96-140).
Description
Recombinant Human a-Synuclein, produced in E. coli, is a single, non-glycosylated polypeptide chain consisting of 140 amino acids. It has a molecular mass of 14.4 kDa. Note: The actual molecular weight observed on SDS-PAGE might be higher. The protein undergoes purification using proprietary chromatographic methods.
Physical Appearance
Clear, colorless solution that has been sterilized by filtration.
Formulation
The protein solution (1 mg/ml) is supplied in a buffer containing 20 mM Tris-HCl (pH 7.5), 0.1 M NaCl, and 1 mM MgCl2.
Stability
For short-term storage (up to 2-4 weeks), the product can be stored at 4°C. For extended storage, it is recommended to freeze the protein at -20°C. Adding a carrier protein such as HSA or BSA (0.1%) can further enhance stability during long-term storage. Avoid repeated freezing and thawing.
Purity
The purity is determined to be greater than 95.0% using SDS-PAGE analysis.
Synonyms
Alpha-synuclein, Non-A beta component of AD amyloid, Non-A4 component of amyloid precursor, NACP, PD1, PARK1, PARK4, MGC110988, a-Synuclein, SNCA.
