Oligosaccharide analysis of the mouse/human chimeric anti-CD20 IgG1s

	Relative composition of oligosaccharides (%)a
Antibody	G0	G1	G2	G0F	G1F	G2F	Fu(−)b
Nonfucosylated anti-CD20	64.0	33.0	3.0	n.d.c	n.d.	n.d.	100
Fucosylated anti-CD20	n.d.	n.d.	n.d.	41.9	51.1	7.0	n.d.
Rituximab	n.d.	n.d.	n.d.	55.1	40.8	4.1	n.d.

^aEach composition value reflects the relative amount in the total complex- type oligosaccharides detected.

^bRelative amount of nonfucosylated oligosaccharides.

^cn.d.: not detected (less than 2.0%).
