Clones 5 and 15 are cloned transfectants with pigHD_vHSP70-1k-NLuc-mCherry. P. yoelii 17XL was used as a negative control. Relative luciferase activities (relative light units, RLU) from 105 blood-stage parasites before and after mosquito and liver stage development (A), 102 mosquito midgut oocysts (B), or 103 mosquito salivary gland sporozoites (C) are shown. Mean and standard deviations from triplicate wells are plotted.</p
