V. EXAMPLE SPECTRA

The following MALDI-MS spectra (positive reflectron) of Phosphopep-
tide Standard – Enolase (top) and Enolase Digest with Phosphopep-
tides Mix (bottom) mixed with MassPREP DHB matrix were obtained
on a Waters MALDI micro MX. Each spectrum (200 laser shots) was
processed by baseline subtraction.

The following postive mode LC-ESI-MS (TIC) spectra were obtained
using a Waters Alliance 2795 coupled to a Waters ZQ 4000 mass
spectrometer. A 20 pmol/μL solution in 0.02% trifluoroacetic acid
in water was prepared and 30 μL was injected on a Waters BioSuite™
C

3 μm, PA – A, 2.1 x 150 mm column.

VI. STORAGE AND STABILITY

It is recommended that the MassPREP™ Phosphopeptide Standards
vial remain in the foil pouch (in the dark) at room temperature until
use. Once reconstituted in appropriate solvents, the solution can be
used for one week when stored in the dark at 4 °C. For longer term
storage, the solution should be aliquoted into microcentrifuge tubes
and stored at –20 °C.
