CONCURRENT IN-VIVO IMMUNOCONJUGATE BINDING TO MULTIPLE EPITOPES OF VASCULAR PERMEABILITY FACTOR ON TUMOR-ASSOCIATED BLOOD VESSELS

摘要

The present invention provides an immunological preparation comprising not less than two types of conjugate molecules in admixture for concurrent specific binding to a spatially exposed region of vascular permeability factor (VPF) bound in-vivo to a tumor-associated blood vessel. Each conjugate molecule type comprises at least a binding portion of an antibody specific for an epitope present within a spatially exposed region of bound VPF; and an effector moiety covalently bound to the specific binding portion. The immunological preparation has wide uses and applications including analytical studies, in-vivo diagnostic testing, and in-vivo therapeutic treatments.
