Web13 dec. 1999 · In this review emphasis is put on MALDI time-of-flight mass spectrometry of polymers. The selection of an appropriate MALDI matrix, cationization salt and … WebIn this work a MALDI time-of-flight (TOF)MS method for the rapid identification of proteins in whole cells of selected microalgae species was studied. Furthermore, the efficiency of different matrix and solvent systems was tested. MS analyses were performed using an MALDI-TOF mass spectrometer operating in linear positive ion mode.
