Graft copolymers of polycationic species and water-soluble polymers, and use therefor

摘要

In accordance with the present invention, there are provided methods to render cells non-adhesive and/or non-immunogenic with respect to macromolecules typically encountered in culture media or in physiological media. The invention method comprises contacting cells with an effective amount of a composition comprising a polycationic species having water- soluble polymer chains grafted thereon.
