Translation from asymmetrically localized mRNA(ABD-GFP)-NPs in droplet Left panel: Bright field observation of mRNA-NP string-like assemblies. Middle panel: Time dependent accumulation of Phalloidin-568 as label for F-actin. Right panel: Time dependent production of GFP. The direction of the magnetic forces was directed towards the right. Epifluorescence, Scale bar: 20 μm, one frame every 5 minutes.
