Flow cytometry
Cells were fixed and permeabilized as previously described (Kerviel et
al., 2016). Flow cytometry was carried out on the BD FACSJazz (BD
Biosciences) and analyzed on FlowJo v10. Assembled particles of AAV2
were detected by staining with anti A20R (Progen) labelled with
AlexaFluor 594 (Invitrogen).
