ESI-MS analysis of lipid C. Lipid C fractions of L. amazonensis promastigotes untreated (A) or treated with 10 μM tamoxifen (B) were analyzed by ESI-MS in the negative mode. MS2 spectra of ions m/z 849 and 863 (C/D and E/F, respectively) revealed characteristic ions of PI molecules that were identified as PI-(O-18:0/18:1) (G) and PI-(18:0/18:1) (H), respectively.
