In last few years, two important achievements of ionization techniques in mass spectrometry have been developed: matrix- assisted laser desorption ionization (MALDI) and electrospray ionization (ESI). By these innovative techniques, mass spectrometry becomes one of the most important experimental tools for the analysis of biomacromoleculars. In this article, we briefly review the principles, characteristics, sample preparation, matrix selection, instrumentation of MALDI and its current progress in biomacromolecular analysis.
