Figure 2. The LTQ ion–trap MS2 spectrum of S881 indicates that it is a polyisoprenoid–derived molecule.

Figure 2

Values in red denote sulfate–containing dissociation ions. A) A zoom of the m/z = 280–790 region (inset) reveals a number of dissociation ions not obtained via FT–ICR MSn (Figure 1). Two series of dissociation ions separated by 68 mass units are observed; one containing sulfate and denoted by *, and another denoted by °. B) The proposed chemical structure of S881, with observed dissociation ions.
