Fig. 3From: Plant expression and characterization of the transmission-blocking vaccine candidate PfGAP50 PfGAP50-specific titers in rabbit immune sera. Immune sera were analyzed by direct ELISA after the first (day 35), the second (day 63) and third boost (day 91). The threshold for titer definition was twofold the background signal obtained from the pre-immune sera. R1: rabbit 1, R2: rabbit 2Back to article page
