    Αlpha Synuclein Oligomers Have Distinct Secondary Structure Differences Compared to Fibrils.Alpha Synuclein Pre-formed Fibrils (PFF), Type 1 (cat#SPR-322) and Type 2 (cat#SPR-317) do have small secondary structure differences.StressMarq’s Alpha Synuclein PFFs (red) cat#SPR-322, were shown to be taken up by SH-SY5Y cells and transmitted to neuronal iPSCs within 14 days.SDS-Page of Type 1 Human Recombinant Alpha Synuclein Protein Pre-formed Fibrils (SPR-322)Type 1 alpha synuclein Pre-formed Fibrils (SPR-322) seed the formation of new alpha synuclein fibrils from the pool of alpha synuclein monomers (SPR-321) as shown by increased fluorescence intensity by Thioflavin T over time.Immunocytochemistry/Immunofluorescence of Human Alpha Synuclein Protein Protein (SPR-322)Mouse neurocortical primary cells seeded with fluorescently-labelled alpha synuclein PFFsMouse neurocortical primary cells seeded with fluorescently-labelled alpha synuclein PFFs cause endogenous alpha synuclein phosphorylationTEM of Type 1 Alpha Synuclein Pre-formed Fibrils (PFFs) (SPR-322)IHC of Sprague-Dawley rat brain injected with Type 1 human alpha synuclein Pre-formed Fibrils (SPR-322)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)

    Thioflavin T emission curves show increased fluorescence (correlated to tau aggregation) over time in active tau monomers (SPR-327). A greater increase in fluorescence is seen when 50 μM active monomer (SPR-327) is combined with 10 μM of active fibrils (SPR-329 or SPR-330), as the active fibrils seed the formation of new fibrils from the pool of active monomers.
