    TEM of Type 2 Alpha Synuclein Pre-formed Fibrils (PFFs) (SPR-317)Alpha Synuclein Pre-formed Fibrils (PFF), Type 1 (cat#SPR-322) and Type 2 (cat#SPR-317) do have small secondary structure differences.SDS-Page of Type 2 Human Recombinant Alpha Synuclein Protein Pre-formed Fibrils (SPR-317)Type 2 alpha synuclein Pre-formed fibrils (SPR-317) do not seed the formation of new alpha synuclein fibrils from the pool of alpha synuclein monomers (SPR-321) at the same rate as Type 1 alpha synuclein Pre-formed fibrils (SPR-322) as shown by lower fluorescence intensity values of Thioflavin T over time.Primary rat hippocampal neurons show lewy body inclusion formation when treated with Type 1 Alpha Synuclein Protein Pre-formed Fibrils (SPR-322) (D-F), but not when treated with Type 2 Alpha Synuclein Protein Pre-formed Fibrils (SPR-317) (A-C).Toxicity results comparing Active Human Recombinant Alpha Synuclein Pre-formed Fibrils (Type 2) and Active Human Recombinant Alpha Synuclein Pre-formed Fibrils (Type 1)LDH assay shows effect of alpha synuclein PFFs on mouse primary neuronsMTT assay effects of alpha synuclein PFFs on mouse primary neurons
