Promega 6 x 5 LC-MS/MS Peptide Reference Mix
The 6 x 5 LC-MS/MS Peptide Reference Mix is a unique reagent designed to monitor liquid chromatography (LC) and mass spectrometry (MS) instrument performance and assist in method development and optimization.
Manufacturer: Promega V7495
- Mixture of 30 peptides; 6 sets of 5 isotopologues of the same peptide sequence
- Amino acids prone to artificial post-translational modification (i.e., methionine, asparagine, etc.) were excluded from the sequences
- None of the peptides have internal lysines or arginines and will therefore not be affected by trypsin or Lys-C
- There is a mass separation of at least 4 Daltons between the isotopologues, so that even low-resolution instruments can distinguish the masses
