  • Publication number: 20100303893
    Abstract: Specific modifying agent is coupled to an anti-tumor protein on a certain site. It conquers the disadvantages which include high antigenicity, short circulating half-life, nonuniform modified sites, inhomogeneous component, reduced activity and uncontrollable quality of the products prepared by non-specific modifying method. The anti-tumor protein coupled with specific modifying agent can be used for the treatment of tumor and for manufacturing an anti-tumor medicament.
