Collision-induced dissociation spectrum of peak 632 m/z. Nano-electrospray FTICR instrument was used in negative ion detection mode. The loss of one hexose followed by the loss of another hexose and water yielded an N-acetyl-neuraminic acid (m/z 290). This composition corresponds to sialyllactose (2 Hex+1 NeuAc).
