Figure 1From: RNAi-mediated silencing of Trichinella spiralis serpin-type serine protease inhibitors results in a reduction in larval infectivityDetection of siRNA delivery to T. spiralis larvae via fluorescence microscopy. Larvae were transfected with FAM-labelled control siRNA by incubation. A Some larvae begin to moult after incubation for 12Â h. B Uptake of FAM-labelled siRNA into larvae under the fluorescence microscope. C Absence of fluorescence in untreated larvae.Back to article page
