Labeling of the Schistosoma mansoni Tegument

Methods Mol Biol. 2020:2151:65-74. doi: 10.1007/978-1-0716-0635-3_6.

Abstract

Schistosomes are deadly pathogens responsible for the neglected tropical disease schistosomiasis. The parasite's virulence is aided by a skin-like tissue called the tegument. The study of the tegument is hampered by a lack of tools suitable for visualizing the tissue. Here we describe a novel methodology employing fluorophore-conjugated dextrans that allows specific fluorescent labeling of the tegument and that is compatible with downstream fluorescence-labeling techniques including phalloidin labeling, RNA FISH, and immunofluorescence.

Keywords: Dextran; Fluorescence; Fluorescence in situ hybridization; Immunofluorescence; Phalloidin; Schistosome; Tegument.
