The present invention discloses a method for the enzyme-mediated, site-specific, in-vivo precipitation of a water soluble molecule in an animal. The enzyme is either unique to tumor cells, or is produced within a specific site (e.g., tumor) at concentrations that are higher than that in normal tissues. Alternatively, the enzyme is conjugated to a targeting moiety such as an antibody or a receptor-binding molecule.
本发明揭示了一种酶介导的、特异位点的、体内沉淀水溶性分子的方法。该酶要么是肿瘤细胞特有的,要么在特定部位(如肿瘤)内产生的浓度高于正常组织中的浓度。另外,该酶可以与靶向基团(如抗体或受体结合分子)结合。
