a.) PAMAM dendrimer generation 1.5 anions used for positive to negative charge inversion of bradykinin +1/+2 in Q0; b.) bradykinin +1/+2 ions passed into Q0 for first ion/ion reaction; c.) Q1 isolated bradykinin −1 ions passed into Q2 for second charge inversion reaction; d.) isolated DAB generation 5 +9 ions previously stored in the Q2 collision cell; and e.) charge inversion of bradykinin −1 produced by reaction of ions in panels c. and d., giving double charge inversion of bradykinin. The asterisk represents an ion produced from DAB dendrimer isolation.
