Here, we present a protocol for the isolation of increasingly insoluble/aggregated alpha-synuclein (α-syn) from post-mortem human brain tissue. Through the utilization of buffers with increasing detergent strength and high-speed ultracentrifugation techniques, the variable properties of α-syn aggregation in diseased and non-diseased tissue can be examined.
