Fig. 4From: The Pfs230 N-terminal fragment, Pfs230D1+: expression and characterization of a potential malaria transmission-blocking vaccine candidateIntact mass analysis of purified Pfs230D1+ (non-reduced and reduced). Representative deconvoluted mass spectra of non-reduced and reduced Pfs230D1+. Inset shows zoom of 21,321.0 Da (non-reduced) and 21,326.1 Da (reduced) corresponding to theoretical masses of 21,321.3 Da and 21,325.3 Da, respectively. Mass additions with second species originating of ~ + 156 Da corresponds to additional N-terminal Arg residue as confirmed by LC/MS peptide mapping (Fig. 5). The reported averages ± 1SD were calculated from three independent experimentsBack to article page
