Deconvolving micrographs of Plasmodium-infected RBCs show that GSL-II, which binds to Plasmodium N-glycans, colocalizes with rhoptries (row A) and the ER (row B) but does not colocalize with apicoplasts (row C), the parasitophorous vacuole (row D), or the food vacuole (row E). In each case GSL-II is labeled red with Alexafluor 594, while antibodies labeled green with Alexafluor 488 are against RhopH3 (rhoptries), Pf39 (ER), and food vacuole (DPAP1). Alternatively, GFP is targeted to apicoplasts (ACPleader-GFP) and the parasitophorous vacuole (ACPsignal-GFP). Control experiments with anti-GFP antibodies show that both apicoplasts and parasitophorous vacuoles are accessible to exogenous probes. The nature of the glycosylated proteins is not known
