α-Synuclein seeds have been identified in various tissues in patients with synucleinopathies. We have developed real-time quaking-induced conversion combined with immunoprecipitation, a method that enables the detection of α-synuclein seeds from the serum of patients with synucleinopathies. This method can lay the foundation for the biological diagnosis of synucleinopathies.
