Fig. 3: Workflow for determining the tau interactome by AP-MS.

A DIV13 primary neurons, transduced with AAV’s to express eGFP, eGFP-TauWT or eGFP-TauP301L were lysed in 1% Triton-X-100 lysis buffer and the cell lysates were immunoprecipitated with GFP-Trap® magnetic beads. The samples were digested on the beads and then labelled with TMT reagents and pooled before analysis by LC–MS/MS. Figure created with BioRender.com.
