Fraction	Observed mass (m/z)	Chemical composition	Theoretical mass (m/z)
1	2,567.68	3 HexN, 2 Kdo, 3 Hep, 5 Hex, 3 P	2,567.69
2	2,301.56	3 HexN, 3 Kdo, 3 Hep, 2 Hex, 3 P	2,301.58
3	2,486.57	2 HexN, 2 Kdo, 3 Hep, 5 Hex, 4 P	2,486.58
4	2,220.47	2 HexN, 3 Kdo, 3 Hep, 2 Hex, 4 P	2,220.48

^aThe molecular mass was determined by charge-deconvoluted negative-ion ESI FT-ICR MS (spectra not shown).
