Fig. 1From: Detection and quantification of Plasmodium falciparum in human blood by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry: a proof of concept studyMALDI-TOF spectra of Plasmodium falciparum and negative controls. An example of mass spectra in the sample range 1000–20.000 m/z. A = Negative control of uninfected erythrocytes. B = Positive sample with 3,1% 3D7 Plasmodium falciparum-infected erythrocytes. Each peak in the spectra represents proteins of a specific charge and size. A full description of peak differences can be found in Table 1. Plasmodium cultures and negative controls were prepared using the same protocols. See Methods section for detailsBack to article page
