II. STORAGE AND STABILITY
Upon receiving the sample, store immediately at -20 °C. The lyophilized
powder is stable at -20 °C until the expiration date printed on the label.
Once reconstituted, the solution should be used immediately for best
performance. Stability can be extended by freezing samples at -20 °C.
III. RECONSTITUTION OF MASSPREP PROTEIN STANDARD MIX
FOR HPLC/UPLC USE
Each vial of the MassPREP Protein Standard Mix contains approximately
123 µg of total protein. Table 2 outlines the individual concentra-
tions. For ACQUITY UPLC BEH C
4
1.7 μm, 2.1 x 50 mm column evalu-
ation (P/N 186004495) the recommended reconstitution volume is
100 μL of 0.1% trifluoroacetic acid in water with a 5 µL load to make
a sample containing 1228 ng/ µL of total protein.

MSDS information: Waters Protein and Peptide Standards contain
various non hazardous peptides in powder form. They are for laboratory
use only, solely for purposes of scientific experimentation, analysis,
research or development. Waters Protein and Peptide Standards
should be used only as directed and in accordance with good
laboratory practice. All Waters Digestion Standards are non hazardous
as defined by OSHA’s Hazard Communication Standard, 29 CFR
1910.1200(c) and Appendix A and B, and are thus exempt from the
requirements of the Hazard Communication Standard, including the
requirement to supply MSDSs.
