Lactosamine oligosaccharides and method for producing the same
 A method for producing an N-acetyllactosamine oligosaccharide, comprising the steps of: PA1 adjusting a sulfate group content of keratan sulfate; PA1 allowing an enzyme having an ability to cleave a glycosidic linkage of keratan sulfate to act on the keratan sulfate with the adjusted sulfate group content to obtain a sulfated N-acetyllactosamine oligosaccharide; and PA1 completely desulfating said sulfated N-acetyllactosamine oligosaccharide.
