Figure 2: The native MS spectrum for IMP-1 under positive observation mode from 0-4000 m/z.

Figure 2:

IMP-1 concentration used was 10 μM in 100 mM ammonium acetate, pH 7.5. The dominant peaks are at 2,557.9979 m/z, 2,842.3565 m/z, and 3,197.0346 m/z corresponding to the masses of ZnZn-IMP-110+, ZnZn-IMP-19+, and ZnZn-IMP-18+, respectively.
