posted on 2021-02-26, 18:31 authored by Daniel Hirschberg, Bertil Ekman, Jeanette Wahlberg, Eva LandbergAnalysis was performed in the positive reflector-mode using 4-chloro-α-cyanocinnamic acid as matrix. Peptides from IgG2 and IgG3 have identical amino acid sequence, thus assigned IgG2/3. Samples were collected from a normoprolactinaemic healthy individual (a) and a patient with hyperprolactinaemia (b). Symbols denote individual monosaccharides as explained in the figure.
