Abstract:

In this paper, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry(MALDI- TOF MS) was used for measuring the relative molecular mass of polypeptides, and the matrixes, solvents, and adding cationic reagents were investigated for optimized determinations.

Key words: Matrix-assisted laser desorption/ionization time of flight mass spectrometry, Polypeptides, Deter- mination of relative molecular mass
