From: Life-span of in vitro differentiated Plasmodium falciparum gametocytes
In vitro longevity of Plasmodium falciparum gametocytes of 3D7, NF54 and one clinical isolate (JH013) of hydroethidine (HE) stained and analysed by flow cytometry. Mean (and SD) maximum longevity of gametocytes is shown in days. Viability of gametocytes is assessed by flow cytometry measuring the percentage of positive fluorescent cells (PPFC) of 50,000 erythrocytes gated against negative control (uninfected erythrocytes stained by HE). All strains were tested at least three times. The figure also shows a scatter chart with a trend line and equation made using log.transformed gametocytaemia data from flow cytometry displayed on the y-axis of the graph.
