Fig. 1. Relocalization of
SpII
* to nuclear foci following treatment
of normal cells with 8-MOP plus UVA light. The localization of
SpII
* in the nucleus of undamaged normal human lymphoblastoid
cells or lymphoblastoid cells treated with 8-MOP plus UVA light (6 kJ
m-2) was examined by immunofluorescence with purified monoclonal
anti-
-spectrin antibody. Counterstaining for the DNA-specific dye DAPI
is shown in the middle panels. In the bottom panels, the fluorescent signal
for DAPI was overlaid on that for anti-
-spectrin. Cells were fixed for
staining 15 hours after treatment with 8-MOP plus UVA.
