Negatively charged specific affinity reagents.

摘要

An in vivo imaging or therapeutic method including administering to a mammal a specific affinity reagent including a physiologically compatible polymer bonded to one or more specific affinity molecules capable of selectively binding to a predetermined substance or class of cells, and one or more reporter groups capable of providing detectable contrast between the predetermined substance or class of cells and cells or substances of the mammal to which the specific affinity reagent does not bind, or of killing cells of the predetermined class.
