  • Patent number: 7771940
    Abstract: Compositions and methods are provided for detecting and measuring DNA-binding proteins. The compositions and methods permit the simultaneous or near-simultaneous detection of multiple DNA-binding proteins in a multiplex or array format, and can be used to generate profiles of DNA binding activity by proteins, specifically, transcription factors. Multiple protein-DNA binding events in a single sample may be detected and quantitated in a high-throughput format.

  • Patent number: 7399589
    Abstract: The present invention provides a hybridization method and kit for the detection and measurement of biological molecules. A test sample containing the biological molecules of interest is hybridized with an unlabeled or optionally a detectably-labeled complementary biomolecule to form a double-stranded hybrid immobilized to a solid phase. The immobilized hybrid may be detected with an entity which specifically recognizes an RNA:DNA hybrid, followed by analyses and quantification. Therefore, the present invention provides a method and kit to detect and measure biological molecules that is simple to use, highly specific, sensitive, and accurate for screening a plurality of biological molecules.

  • Patent number: 7001776
    Abstract: This invention provides a novel device and method for preparing cytology slides. The device comprises a book-like form including an absorbent material and filter attached to the inside surface of a front cover and a cytology slide removeably attached to an inside surface of a back cover. A sample is removed from the body of a patient, placed in a liquid-based solution, and then on the filter. When the book-like form is closed, the sample is effectively transferred to the slide. The device can be modified so that a plurality of slides are prepared at the same time.

  • Publication number: 20040203031
    Abstract: The invention provides a diagnostics assay for measuring the responsiveness to a drug by comparing the mRNA levels of a gene that responds to the drug, such as a steroid, to the mRNA levels of a gene that does not respond to the drug. Methods according to the invention are useful for predicting the ability of a patient (or a tissue, body fluid or cell sample in vitro) to respond to a drug or steroid at any stage of their treatment (i.e., before, during or after), and to monitor the patient (or a tissue, body fluid or cell) over time to assess continued responsiveness to the drug or steroid.

  • Publication number: 20040126796
    Abstract: Methods and compositions are provided for extracting DNA from tissues, hair, teeth, bone, plant material, solid matrices and other samples from which DNA extraction is generally regarded as being difficult. DNA may quickly be extracted from samples, for example, in just 5 minutes to 2 hours, without enzymatic digestion or the use of toxic organic chemicals such as phenol, chloroform, guanidine thiocyanate or 2-mercaptoethanol.

  • Publication number: 20030175828
    Abstract: The methods of the invention relate to signal amplification for assays detecting a particular target analyte. Amplification is accomplished by utilizing one or more binding partner pairs to generate signal amplification. The present invention concerns a method to improve detection or quantitation of a target analyte in a sample by amplifying the detector signal which comprises reacting a target analyte with a conjugate consisting of a detectably labeled substrate specific for the enzyme system, said conjugate reacts with the analyte dependent enzyme activation system to form an activated conjugate which deposits substantially wherever receptor for the activated conjugate is immobilized, said receptor not being reactive with the analyte dependent enzyme activation system. In another embodiment the invention concerns an assay for detecting the presence or absence of a target analyte in a sample to amplify the reporter signal.

  • Publication number: 20020012936
    Abstract: A non-radioactive hybridization assay and kit for the detection of genetic defects, microbial infections or viral infections, such as human papillomavirus. A test sample is treated with a base and incubated with nucleic acid probes, diluted in a neutralizing buffer, specific for target nucleic acids. The hybrids are captured onto a solid phase coated with an anti-hybrid antibody, unhybridized probe is eliminated, and the bound hybrid detected.

  • Patent number: 6326136
    Abstract: Conjugate probes are prepared in a one step process by incubating a macromolecule and a labeling group with an unsaturated polyaldehyde as the conjugating agent. The conjugating agent is capable of bonding virtually any labeling group to a macromolecule. Conjugate probes have been shown to have a high degree of specificity and exhibit a strong signal with minimal background.
