Analysis of Gene Expression in Fasciola hepatica Juveniles and Adults by In Situ Hybridization.

In situ hybridization (ISH) is a technique used for the spatial localization of nucleic acids within tissues and cells. It is based on the ability of labeled nucleic acids (probes) to hybridize under the right conditions with the nucleic acids present in fixed biological specimens. In this chapter, we describe protocols for detection of RNA by ISH using digoxigenin (DIG)-labeled probes for Fasciola hepatica adults (in cryosections, given their large size) and for newly excysted juveniles (NEJs, which are ideally suited given their small size for whole-mount ISH). We describe fluorogenic and chromogenic protocols, respectively, but the detection methods can be easily interchanged by using the appropriate enzyme-conjugated antibodies and detection solutions.
