Supplementary Table 2: Glycoforms of the c/MAM peptide ETGATEKPTVIDSTIQSEFPTY detected on a
2
Bruker maXis 4G Q-TOF instrument. The monoisotopic masses of the most intense forms in regard to
3
different charge carriers are given. Glycopeptide species marked with $ could however only be registered on an
4
Ultima Global Q-TOF MS (Waters-Micromass).
