The LASH-EGT and the EP1536Y antibodies were excluded from the screen for the following reasons: (1) the LASH-EGT antibody due to its poor capacity to recognize aSyn pathology in PFF-treated neurons (Fig. 4b, c); and (2) because the new EP1536Y antibody batches we recently acquired were no longer suitable for ICC, as acknowledged by Abcam by removing the ICC recommendation from their datasheet (https://www.abcam.com/alpha-synuclein-phospho-s129-antibody-ep1536y-ab51253.html). The gene discussed is SNCA; the disease is intrahepatic cholangiocarcinoma.
