Promega Corporation announces the release of the 6 × 5 LC-MS/MS Peptide Reference Mix, a novel reagent and software combination. The reagent monitors LC and MS parameters, while the complementary software reports on instrument performance, as well as performance history.

The unique peptide formulation saves time by assessing multiple LC and MS parameters, such as peak height, mass accuracy, dynamic range and sensitivity, in a single run. The AAA-qualified peptides result in accurate reporting of instrument sensitivity and dynamic range. The 6 × 5 LC-MS/MS Peptide Reference Mix can be used in multiple applications, with either neat or complex sample mixtures. The complementary PReMiS Software tool eliminates time-consuming manual calculations, and monitors instrument-to-instrument performance over time.

"With the 6 × 5 LC-MS/MS Peptide Reference Mix, you can check the stability of your LC, the sensitivity and dynamic range of your MS, and monitor instrument performance in every run. And in a matter of minutes, the free software tool reports the results,” says Gary Kobs, senior global product manager at Promega Corporation.

Hardware required to run the PReMiS Software includes a Windows PC with a Dual-Core x86 based processor, 4GB Memory, 100GB hard drive, video 1024 × 768 pixels, and Microsoft Windows XP SP3, Vista 32/64, Windows 7 32/64, or Windows 8 32/64.
