Immunohistochemical detection of activated caspase-3 counterstained with haematoxylin. Original magnification: × 500. Apoptotic cell with sufficient cytoplasmatic material and strong activated caspase-3 positivity (arrow); small apoptotic body with with weak activated caspase-3 positivity (dashed arrow); apoptotic bodies without cytoplasmatic material that would have been positive in samples stained with haematoxylin-eosin, but are not dysplaying any positivity in activated caspase-3 immuno-stained samples (circled)
