From: A novel Pfs38 protein complex on the surface of Plasmodium falciparum blood-stage merozoites
Naturally-acquired humoral IgG immune responses to proteins of Pfs38 complex. Human IgG antibodies against proteins of 6-Cys complex were detected by ELISA in sera from naturally infected patients from Liberia and India. Sera from Denmark were used as a negative control. The dotted line indicates positivity thresholds determined from the mean reactivities +2 SD of 28 sera samples from Danish non-immune volunteers. African and Indian sera with OD above the positive thresholds are considered seropositive for each of the antigen. Bars represent mean ± SEM for 28 sera samples
