Fig. 2From: Adaptation of ELISA detection of Plasmodium falciparum and Plasmodium vivax circumsporozoite proteins in mosquitoes to a multiplex bead-based immunoassayLower range of detection for sporozoites (spz) and recombinant positive control (PC) for circumsporozoite (cs) enzyme-linked immunosorbent assay (ELISA) and cs multiplex-bead assay (MBA). When possible, the absorbance values at λ = 405 nm for four points above and below the cut-off value (indicated by dashed lines) were plotted for csELISA. For csMBA, data points with median fluorescence intensity values minus background (MFI-Bkgd) < 1000 were plotted, up to four points below the cut-off. A Plasmodium falciparum. B P. vivax210.
