Rhoptries are key secretory organelles for Toxoplasma gondii invasion. Here, we describe how to assess the ability of T. gondii tachyzoites to secrete their rhoptry contents in vitro.

Our research on rhoptry secretion is supported by the Laboratoire d’Excellence (LabEx) (ParaFrap ANR-11-LABX-0024) and by the Fondation pour la Recherche Médicale (Equipe FRM EQ. 20170336725) to M.L. M.B.L. is supported by NIH R01AI20846. We would like to thank Julien Marcetteau for the graphic design of the figure and Anita Koshy for helpful comments.
