<p>Extracts from highly synchronized parasites were collected every 8 h, separated by SDS-PAGE, and evaluated by immunoblotting with anti-falstatin antibodies. Each sample of early-ring, late-ring, early-trophozoite, late-trophozite, early-schizont, or late-schizont extracts corresponded to 1.3 × 10<sup>7</sup> parasitized cells. The positions of molecular weight markers (kDa) are indicated. ER, early-ring; LR, late-ring; ET, early-trophozite; LT, late-trophozite; ES, early-schizont; LS, late-schizont.</p
