SDS-PAGE of ~14 kDa A53T Alpha Synuclein Monomer (SPR-325)

Thioflavin T is a fluorescent dye that binds to beta sheet-rich structures such as those in alpha synuclein fibrils. Upon binding, the emission spectrum of the dye experiences a red-shift and increased fluorescence intensity. Thioflavin T emission curves show a limited increase in fluorescence (correlated to alpha synuclein aggregation) over time in A53T alpha synuclein monomers (SPR-325). A much greater increase in fluorescence is seen when 100 uM monomer (SPR-325) is combined with 10 nM of fibrils (SPR-326) as the fibrils seed the formation of new fibrils from the pool of active monomers. Thioflavin T ex = 450 nm, em = 485 nm.

citations: 2

Primary rat hippocampal neurons show lewy body inclusion formation when treated with A53T mutant Alpha Synuclein Protein Pre-formed Fibrils (SPR-326) (B) but not when treated with a media control (A). Tissue: Primary hippocampal neurons. Species: Sprague-Dawley rat. Primary Antibody: Rabbit anti-pSer129 Antibody. Fibrils were diluted to 1 ug/uL in neuronal media consisting of B27, Glutamax, penicillin/strip, and neurobasalA and sonicated for 1 hour in a water bath. The sonicated stock was then used to achieve the final concentration of 1 ug/mL in the wells.

StressMarq Biosciences
catalog: SPR-503


SDS-PAGE of purified human alpha synuclein TNG (A53T, S87N, N103G) monomer (SPR-503) on a 12% Bis-Tris Gel. 2ug and 4ug of total protein were loaded into the respective lanes. Electrophoresis was run at 200V for 45 minutes with fixed voltage using 1X MES running buffer.

Fibril formation and seeding activity of human alpha synuclein TNG mutant measured by ThT in vitro. Human TNG mutant monomers (SPR-503) self-aggregate faster than human wild-type monomers. Human TNG mutant pre-formed fibrils (SPR-504) rapidly seed mouse wild-type monomers, but not human wild-type monomers, similar to the seeding pattern observed for mouse wild-type pre-formed fibrils.
