For electrospray ionization in Fourier-transform mass spectrometry, direct injection of 5Γ10(-14) mol (0.5 Β΅L of 100 nM from a microvolume sample valve) of ubiquitin (8565 Da) into the flowing solvent stream yields a spectrum with 85:1 signal-to-noise ratio, 2-ppm mass accuracy, and isotopic resolut
Up to now, sixteen gibberellins have been isolated and their structure established. Mass spectroscopy of these large number of gibberellin homologues should afford useful information not only for identification but also for structural elucidation of new gibberellins. Recently Wulfson et al. (1) repo
