Figure 2: MALDI-TOF analysis of oxytocin disulphide bond integrity: The oxytocin peak fraction eluting at 10.6 min was subjected to MALDI-TOF mass analysis before (A) and after (B) reduction with dithiothreitol (DTT). The shift of 2 amu mass, in oxytocin and its Na and K adducts after reduction with DTT indicates addition of 2-H atoms.
