great product , easy to use software.
Application Area: LC-MS instrument QC
"I got a demo sample from Promega sales and tried it. Good peptide standards over range of rntention time and concentration. The software is easy to use too. Then I started buying it."
A Complete Solution for Monitoring LC and MS Instrument Quality Control and Performance. In combination with an accompanying software tool, the 6 × 5 LC-MS/MS Peptide Reference Mix provides a convenient way to assess LC column performance and MS instrument parameters, including sensitivity and dynamic range.
Consists of 30 peptides; 6 sets of 5 isotopologues of the same peptide sequence, differing only in the number of stable, heavy-labeled amino acids incorporated into the sequence
Labels are uniform 13C and 15N atoms.
Isotopologues are chromatographically indistinguishable; however, since they differ in mass, they are clearly resolved by mass spectrometry.
The isotopologues of each peptide are present in a series of tenfold dilutions. This format allows assessment of instrument dynamic range and sensitivity from a single run.
The 6 × 5 LC-MS/MS Peptides are AAA-qualified for accurate monitoring, and are compatible with multiple applications and neat or complex mixtures.
