A, mass chromatogram of m/z 852 from LC-ESI/MS of the oligosaccharides derived from fraction 181:IV from human embryonic stem cell line SA181. B, mass chromatogram of m/z 852 from LC-ESI/MS of the oligosaccharides derived from reference H type 1 pentaglycosylceramide (H5-1; Fucα2Galβ3GlcNAcβ3Galβ4Glcβ1Cer). C, mass chromatogram of m/z 852 from LC-ESI/MS of the oligosaccharides derived from reference H type 2 pentaglycosylceramide (H5-2; Fucα2Galβ4GlcNAcβ3Galβ4Glcβ1Cer). D, mass chromatogram of m/z 852 from LC-ESI/MS of the oligosaccharides derived from reference Lea pentaglycosylceramide (Lea-5; Galβ3(Fucα4)GlcNAcβ3Galβ4Glcβ1Cer). E, mass chromatogram of m/z 852 from LC-ESI/MS of the oligosaccharides derived from reference Lex pentaglycosylceramide (Lex-5; Galβ4(Fucα3)GlcNAcβ3Galβ4Glcβ1Cer). The retention times of the molecular ions are given in italic type.
