Fig. 3. Differential distribution of RNF17 protein isoforms. Adult testis sections were immunostained with anti-sera 1774 in red (A) and GP8 in green (B). The seminiferous tubule shown is in stage X. In the merged image (C), selected RNF17 granules are indicated by arrows in the spermatocytes, and by arrowheads in the spermatids. Scale bar: 10 µm.
