Abstract
A Chromatography medium having the properties of high virus adsorption and high fluidity, and a method for producing a virus vaccine using these are provided. The Chromatography medium is formed by binding a sulfated polysaccharide to porous particles having an exclusion limit molecular weight of 6000 Da or less when pure water is used as mobile phase and standard polyethylene glycol is used and an average particle size in the range of 30-200 μm.
Claims5
A chromatography medium, formed by binding a sulfated polysaccharide to porous particles having an exclusion limit molecular weight of 6000 Da or less when pure water is used as mobile phase and standard polyethylene glycol is used, wherein the chromatography medium is of General Formula (1) below:
- X—O—CH2—C(OH)H—CH2—NH—CH2—Z (1)
- wherein in Formula (1), X is the porous particle have an average particle size in the range of 30-200 μm, bonded to X is an oxygen originating from hydroxyl of the porous particle, Z is the sulfated polysaccharide, and C bonded to Z is a carbon originating from the reductive end of the sulfated polysaccharide, wherein sulfated polysaccharide is a ligand, and a limiting viscosity of the sulfated polysaccharide is in the range of 0.40-0.90 dL/g.
