Fig. 4. ORM1 (alpha-1-acid glycoprotein) exhibits extensive glycan structure microheterogeneity. ORM1 protein was immunoprecipitated form plasma and glycans structures found at four different sites are shown. The four glycosylation sites on which these structures were found are shown as color-coded circles in a box and for every glycan plausible structure, the glycosylation site is indicated.
