Detection of myosin in blood stage parasites fixed with MeOH and stained with IFA using anti-skeletal myosin monoclonal Abs. Staining patters typical of all such Abs used in this study are shown in A) and C) , showing the fluorescence associated with developing intraerythrocytic parasites (A) and released merozoites (C). Note the bright spots of fluorescence at merozoite pole (Δ). B) and D) show the respective, corresponding DIC images.Webb SE, Fowler RE, O'Shaughnessy C, Pinder JC, Dluzewski AR, Gratzer WB, Bannister LH, Mitchell GH.
