Immunolocalization of EgHR3 in protoscoleces (PSCs) and adult worms of E. granulosus. EgHR3 in PSCs: a and e, showing normal structure of PSC; b and f, stained with DAPI; c and g, probed with normal mouse serum and anti-EgHR3 antiserum, respectively; d and h, combined a, b and c, or e, f and g, respectively, showing co-localization of nucleus and EgHR3 (A). EgHR3 in adult worms of E. granulosus: i and m, showing normal structure of adult worms; j and n, stained with DAPI; k and o, probed with normal mouse serum and anti-EgHR3 antiserum, respectively; l and p, combined i, j and k, or m, n and o, respectively, showing co-localization of nuclei and EgHR3 (B).
