Dual immunolocalization of HEI10 and ZEP1 in WT meiocytes.

<p>(A) Early zygotene. (B) Late zygotene, HEI10 signals localize on ZEP1 linear signals. (C) Early pachytene, HEI10 signals overlap well with ZEP1 signals. (D) Late pachytene, prominent HEI10 foci localize on ZEP1 linear signals. Scale bars, 5 µm.
