Immunocytochemistry positive and negative control: Immunolocalization of caspase-3 and caspase-8 (b and d) in HeLa cells treated with 40 μM of cisplatin. Nuclear and cytoplasmatic brownish staining is observed for treated cultures indicating occurrence of active caspase-3 (b) and caspase-8 (d) (Microscope objective 40 × 0.75). No staining for active caspase-3 (a) or caspase-8 (c) was observed for control non-treated cells (Microscope objective 63 × 1.23).
