Figure 2.9. Schematic of a matrix-assisted laser desorption/ionization (MALDI) event. The SEM micrograph depicts sinapinic acid-equine myoglobin crystal from a sample prepared according to the dried drop sample preparation method. In the desorption event neutral matrix molecules (M), positive matrix ions (M+), negative matrix ions (M-), neutral analyte molecules (N), positive analyte ions (+), and negative analyte ions (-) are created and/or transferred to the gas phase.

Matrix assisted laser desorption ionization time-of-flight (MALDI-TOE) mass spectrometry was carried out with a PerSeptive Biosystems Voyager-DE-RP MALDl-TOF mass spectrometer. A 337-nm UV nitrogen laser producing 3-ns pulses was used in the reflectron mode. The samples were prepared by mixing 10 pi of a 0.1 M HAc solution of the sample with 20 pi of a solution of 3 mg/1 a-cyano-4-hydroxy cinnamic acid in wafer. One pi of that solution was loaded on the gold-sample plate. [Pg.78]

The 1 1 mixtures of strands 19 and 20 (0.5 mM each) were prepared in CH2CI2, methanol, and water. The samples were subjected to redox conditions (I2) for various lengths of time and then examined by matrix assisted laser desorption ionization (MALDI). As expected, 19 and 20 sequence specifically associated with each other in CH2CI2, leading to the disulfide cross-linked 19-20 as the major product. With an increasing ratio of methanol in CH2CI2, the cross-linked 19-20 stUl appeared as the dominant product. The same phenomenon was observed in pure methanol and even in water (Fig. 9.14b). The sequence dependence of the cross-linking of 19 and... [Pg.224]
