Methylcalcein blue

A continuous-flow post-colunm ligand-exchange reaction of phosphopeptides with fluorescent Fe " -methylcalcein blue (MCB) coupled to ESI-MS has been proposed as alternative means to selectively detect phosphopeptides in tryptic digests [45]. The system detects the presence of a phosphopeptide in the LC effluent as a peak in the MCB reporter trace, measured by SIM. Because not all phosphopeptide reacts with Fe, the free phosphopeptide can be simultaneously characterized by MS or MS-MS. Using conventional-flow ESI-MS (100 pl/min), detection hmits were 2 pmol/pl. [Pg.531]
