Fig. 3. Distribution of XStau during oogenesis. Immunofluorescence was performed using XStau antibodies and Alexa-568 conjugated secondary antibody to detect the distribution of XStau in oocytes of the following stages: (A) stages I-II, (B) stages III-IV and (C) stages V-VI (Dumont, 1972). Confocal images are shown. Scale bars: 100 µm. Arrowheads show enrichment of XStau in the vegetal cortex of stage III-V oocytes.
