The fully human monoclonal antibody PfNPNA-1 against (NPNA)3 specifically labels Plasmodium falciparum in an IFA. PfNPNA-1 is a promising candidate for evaluation for the prevention of malaria.
Figure 1 Indirect immunofluorescence assay (IFA) on Plasmo-dium falciparum sporozoites.
Anti-sporozoite activity of the PfNPNA-1 VH/κ moleculewas clearly evident in an immunofluorescence assay (IFA) with P. falciparum sporozoites.

Figure 2 Competition ELISA was carried out to approximate the affinity of binding.
Binding affinity ofthe monovalent PfNPNA-1 for (NPNA)3 comparedfavourably with values previously reported for a panel ofconventional murine monoclonal antibodies directedagainst the repeat epitope, which also have affinitiesin the µM range.
