ABSTRACT:
Methods and compositions useful for the separation of viruses, including retroviruses and vital vectors, from preparations are disclosed. Sulfated oligosaccharides with at least about 6 .mu.moles sulfate per gram of oligosaccharide are provided. In one aspect, a sulfated oligosaccharide of the present invention may be used in the purification of a virus, such as a lipid envelope virus. The present invention also discloses methods for the removal of a contaminating virus from a preparation, such as biologic therapeutics.
