HEK293FT cells were seeded at 2.5 × 104 cells per well in a Matrigel-coated 96-well plate and transfected with 3xFlag-HD-LRRK2 and either 2xmyc-Gus, 2xmyc-Rab29 or mutant 2xmyc-Rab29 Q67L plasmid. 24 hours after transfection cells were fixed and stained, then imaged and analyzed on a high throughput Cellomics VTI arrayScanner as previously described [21 (link)].
