Stressmarq developed active alpha synuclein protein fibrils that can be used to induce endogenous alpha synuclein phosphorylation and subsequent Lewy body inclusion formation in neuronal cell culture or for in vitro oligomerization studies.

Our active alpha synuclein protein fibrils seed the formation of new fibrils from active alpha synuclein monomers.
