Fig 7. Immunohistochemical localization of TOR3A in the porcine oviduct.

Strong immunostaining for TOR3A protein was only observed in the oviductal wall of the inseminated sows (Fig 7A, magnified in 7A1). The labelling was absent in non-inseminated animals (Fig 7C magnified in 7C1) as well as in the corresponding negative controls for the inseminated (Fig 7B, magnified in 7B1) and non-inseminated sows (Fig 7D, magnified in 7D1). In all figures, scale bars correspond to 100 μm.
