Fig. 3From: Analysis of apoptosis related genes in nurses exposed to anti-neoplastic drugsApoptosis assay in exposed and unexposed nurses. a Unexposed nurses; (b) exposed nurses. Apoptosis was measured by the annexin V assay using flow cytometry. The assay gives information about the number of live cells (AV−/PI-), apoptosis cells (AV+/PI-), necrotic cells (AV−/PI+) and secondary necrosis cells (AV+/PI+)Back to article page
