    • A method is disclosed for modifying an oligonucleotide, which method has application to the detection of a polynucleotide analyte. An oligonucleotide is reversibly hybridized with a polynucleotide, for example, a polynucleotide analyte, in the presence of a 5′-nuclease under isothermal conditions. The polynucleotide analyte serves as a recognition element to enable a 5′-nuclease to cleave the oligonucleotide to provide (i) a first fragment-that is substantially non-hybridizable to the polynucleotide analyte and (ii) a second fragment that lies 3′ of the first fragment (in the intact oligonucleotide) and is substantially hybridizable to the polynucleotide analyte. At least a 100-fold molar excess of the first fragment and/or the second fragment are obtained relative to the molar amount of the polynucleotide analyte. The presence of the first fragment and/or the second fragment is detected, the presence thereof indicating the presence of the polynucleotide analyte. The method has particular application to the detection of a polynucleotide analyte such as DNA. Kits for conducting methods in accordance with the present invention are also disclosed.

    • A method for the treatment of cancer is disclosed which is capable of directing supra-lethal doses of radiation, called Hot-Spots, virtually exclusively to the cancer. The present invention involves a multi-step therapy process and includes a class of novel chemical agent. In accordance with the present invention, it was discovered that soluble precipitable materials can be made to accumulate as non-digestible precipitates in the extra-cellular fluid in the cancer region as a result of non-mammalian enzyme action. Precipitate accumulation is achieved by prior administration of a bispecific reagent with a non-mammalian enzyme moiety and a agent capable of binding to non-endocytosing receptors of target cancer cells. A soluble radioactive toxic therapeutic agent is then administered, the soluble toxic therapeutic agent being adapted to be converted by the non-mammalian enzyme moiety of the bound bispecific reagent into a new form which is retained adjacent to the target cancer cells for an extended period of time, thereby generating Hot-Spots which non-selectively kill all cells in the cancer region adjacent to the bispecific reagent.

    • A method for the accumulation of trace-labeled or therapeutic insoluble molecules in targeted cells of a living host for purposes including diagnosis, therapy, and research in cell biology. The method enables soluble precipitable materials, which can be trace-labeled or therapeutic, to be made to accumulate as non-digestible precipitates in targeted cells as a result of enzyme action within the targeted cells. Accumulation is achieved by administering to the living host a soluble binary reagent having a targeting agent attached to a chemical agent which is a soluble precipitable material. The binary reagent binds to antigenic receptors on targeted cells which endocytosed the binary reagent and transport it into the lysosomes where enzymes detach the soluble precipitable material from the targeting agent, causing it to precipitate, accumulate, and be retained in the cells. Continuing the administration of the binary reagent forms an accumulation of precipitate which becomes a stable insoluble tracer agent or a stable insoluble therapeutic agent in the targeted cells. The method can be applied to the diagnosis and scanning of certain diseased states, and to the therapy of certain diseased states, such as cancer, by generating supra-lethal micro-regions of radiation around targeted cells called Hot-Spots which are capable of killing, non-specifically, all cells in the immediate micro-region.
