PfGRP170 (HSP110) Interacts with BiP. (C). In vivo interaction of PfGRP170 and BiP. PfGRP170-GFP-DDD parasites were paraformaldehyde fixed and stained with anti-GFP and anti-BiP. A Proximity Ligation Assay (PLA) was then performed. The scale bar is 5μm. A negative control using anti-GFP and anti-PfPMV is shown in (D). (E). Asynchronous PfGRP170-GFP-DDD parasites overexpressing PfBiP-Ty1were paraformaldehyde fixed and stained with anti-GFP (PfGRP170), anti-Ty1 (PfBiP-Ty1-KDEL), and DAPI to visualize the nucleus. The images were taken with Delta Vision II, deconvolved, and are displayed as a maximum intensity projection. The scale bar is 5μm.
