Glycoforms detected in mouse brain and liver for 9 N-glycosylation sites of Prolow-density lipoprotein receptor-related protein 1. The nomenclature proposed by the Functional Glycomics Consortium is used. “X”s through residues indicate that the glycan was also detected lacking that particular building block. From the mass spectrometry data, the linkages usually cannot be determined, only the composition of the oligosaccharide.
