Figure 2

Electropherograms of (a) FMX-8 MOD, ActiSM, and ActiPro medium and (b) FMX-8 MOD, ActiSM, and ActiPro medium spiked with standard vitamins (50 µM) analysed with BGE: 100 mM phosphoric acid, 55 mM T-EthA. Applied voltage 13 kV; resulting current 40–46 µA. PM: pyridoxamine, B1: thiamine, B3: nicotinamide, PN: pyridoxine, PL: pyridoxal.
