One problem of matrix-assisted laser desorption ionization coupled to time-of-flight mass spectrometry is the moderate mass accuracy that typically can be obtained in routine applications, Here we report improved mass accuracy for peptides, even when low amounts and complex peptide mixtures are used
Quantitative aspects of oligonucleotide analysis by matrix-assisted laser desorption/iotion (MALDI) mass spectrometry remain largely unexplored relative to the efforts that have been devoted to quantitative peptide and protein analysis. The successful quantitation of these other biopolymers coupled
