Fig. 5. Colocalization of Pdc and Gβ
related to light conditions in
cells of Blepharisma. Distribution of Pdc (red) and Gβ
(green) and their colocalization (yellow) close to the plasma membrane
identified by immunocytochemistry. (A,B) A1–A3, staining of Pdc and
Gβ in dark-adapted cells; B1–B3, Pdc and Gβ in cells exposed
to light. (B) C1–C3, cells after 10 min incubation with 1 µmol
l–1 okadaic acid followed by illumination.
