Sin autolysis peaks and also the matrix ion signals. In MS/MS positive ion mode, for one principal MS spectrum 50 sub-spectra with 50 shots per sub-spectrum were accumulated employing a random search pattern. Collision power was two kV, the collision gas was air, as well as the default calibration was set employing the Glu1-Fibrino-peptide B ([M+H] + 1570.6696) spotted onto Cal 7 positions of the MALDI target. Combined peptide mass fingerprinting (PMF) and MS/MS queries had been performed working with the MASCOT search engine two.two (Matrix Science, Ltd.) that was embedded in to the GPS-Explorer Software program three.six (Applied Biosystems) around the NCBI database using the following parameter settings: 100 ppm mass accuracy, with trypsin cleavage and one particular missed cleavage permitted, carbamido methylation set as a fixed modification, and oxidation of methionine permitted as a variable modification. Moreover, the MS/MS fragment tolerance wasProtein Expression Profiles during Grain DevelopmentThe expression profiles on the 130 protein spots were investigated by hierarchical cluster analysis (Figure 5).
