In the original publication of this article [1] the plasmid name is incorrect in the first sentence of the “K23Q rαSyn expression vector preparation” section of Materials and methods.

The correct and incorrect information is shown below in bold.

  • Correct: DNA sequences coding for human α-synuclein sequence (Accession No. NM_000345.3) amino acid residues 1–140 (wildtype) were amplified and ligated into the pET28 vector with an N-terminal His-tag (EMD Biosciences) and sequences were confirmed.

  • Incorrect: DNA sequences coding for human α-synuclein sequence (Accession No. NM_000345.3) amino acid residues 1–140 (wildtype) were amplified and ligated into the pET24 vector with an N-terminal His-tag (EMD Biosciences) and sequences were confirmed.

Furthermore, the original publication contained an incorrrect version of figure 4. The error in this figure is: exponents in the SD50/mg column of panel A are negative, when they should be positive. This correction article contains the correct version of Fig. 4.

End-point dilutions of synucleinopathy BH (a; sample # 081017) or CSF (b; sample # 10/005) samples by αSyn RT-QuIC. Each sample trace represents the average ThT signal of quadruplicate wells. Tables to the right of each graph indicate the concentration of SD50 units calculated by Spearman–Kärber analysis for these, and additional, cases. End-point dilution experiments used for the additional calculated values shown in the upper and lower panels are provided in Additional files 4 and 5, respectively
