Ionization of peptides
WebWe have developed a simple and effective means of using alkylammonium ion-pairing agents, such as cetyltetramethylammonium bromide, to recover matrix assisted laser desorption/ionization mass spectrometric (MALDI-MS) signals from sodium dodecyl sulfate (SDS)-containing protein and peptide samples. WebTo achieve this goal, the use of dimensionless relative retention times (iRT), defined on the basis of peptide standard retention times (RT), has lately emerged as a powerful tool. The robustness, reproducibility and utility of this strategy were examined for the first time in a multicentric setting, involving 28 laboratories that included 24 of the Spanish network of …
