No significant change was seen in the phosphatidylserine externalization of parasitized erythrocytes after exposure sunlight. Flow cytometry histograms (upper panels) showed an apparent increase in PS externalization in mixed-stage pRBC at both 24 (a) and 48 (c) hours after one and two exposures to sunlight, respectively. However, statistical analyses of bar graphs (bottom panels) showed no significant differences (ns). Synchronized late-stage pRBC exposed to solar radiation for 1 h and maintained in the dark for the remainder of 24 h also showed no change in PS externalization, compared to control cultures maintained in the dark (b). n = 2 for (a) and (b); n = 4 for (c)
