Fig. 2. Phospho-histone H3 staining of wild-type and spe-37(gf)/+ sperm.
(A-D) Wild-type. (E-H) spe-37(q89)/+. (A,E) DIC; (B,F) FITC
anti-phosphorylated histone H3; (C,G) DAPI staining of nuclei; (D,H) merge of
DAPI and anti-phospho-H3. Arrow indicates a wild-type spermatid that does not
stain for phospho-histone H3. Scale bars: 5 µm.
