Fig. 2. Mad2 on unattached kinetochores. Mad2 was localized in the
nda3-KM311 mutant cells that were expressing Mis6-HA (top panels).
Mis6-HA was visualized by indirect immunofluorescent staining (red), DNA by
DAPI (blue) and Mad2 by GFP (green). As a negative control, indirect
immunofluorescent staining for HA epitope was performed with cells not
expressing Mis6-HA (lower panels).
