Table III. Reported percentage repartition of un, mono, and disyalylated and fucosylated and unfucosylated N-glycans for the major and intermediate compounds. The significant N-glycans were revealed by the W- test as composition significantly different between PSA and PSA high isoform. PSA high isoform was more disialylaled than the PSA, when PSA is more monosialylated. The percentage of unsialylated compounds is relative comparable for PSA and PSA high isoform. PSA high isoform is more fucosylated than the PSA.

N-glycans	Σ(average intensity N-glycans)		Σ(average intensity significant N-glycans)
	PSA	PSA high isoform	PSA	PSA high isoform
Unsalylated	4.4	4.5	0.3	2.8
Mono Salylated	71.2	43.5	57.4	32.5
Disalylsated	8.3	37.9	5.7	33.0
Fucosylated	53.4	72.9	45.9	67.1
Unfucosylated	30.5	13.0	17.7	1.3
