Symptom: Early eluting peptides are missing (based on monitoring PepCalMix LC-MS test or observing a change in the shape of the proteome TIC).
Test: Use PepCalMix LC-MS test to monitor binding of early eluting peptides. There are a number of very hydrophilic peptides in the PepCalMix which are great for testing the quality of trapping for your LC-MS experiment (IGNEQGVSR – 485.253 m/z, LVGTPAEER – 491.2656 m/z, AETSELHTSLK – 408.5501 m/z).
