  • Patent number: 6969615
    Abstract: The present disclosure is directed to devices, arrays, kits and methods for detecting biomolecules in a tissue section (such as a fresh or archival sample, tissue microarray, or cells harvested by an LCM procedure) or other substantially two-dimensional sample (such as an electrophoretic gel or cDNA microarray) by creating “carbon copies” of the biomolecules eluted from the sample and visualizing the biomolecules on the copies using one or more detector molecules (e.g., antibodies or DNA probes) having specific affinity for the biomolecules of interest. Specific methods are provided for identifying the pattern of biomolecules (e.g., proteins and nucleic acids) in the samples. Other specific methods are provided for the identification and analysis of proteins and other biological molecules produced by cells and/or tissue, especially human cells and/or tissue.

  • Patent number: 6958242
    Abstract: Provided herein are methods for preliminary analysis of suspect samples, which can be used in triaging possible contaminated sites (e.g., sites contaminated or thought to be contaminated by biowarfare agents). In some embodiments, the methods involve testing for the presence of protein in the suspect sample; optionally, the sample can also be tested for the presence of sugar, and/or for pH determination. Specific embodiment methods are carried out in tubes or other reaction vessels, others are carried out in a pad format, and still others are carried out in a test strip format. Kits for carrying out the described methods are also provided.

  • Publication number: 20050115903
    Abstract: The invention relates to a method for extracting nucleic acids of microorganisms contained in a complex mixture, particularly a food mixture, comprising at least the following steps: the mixture is clarified; the microorganisms are retained on a filtering cartridge; said microorganisms are lysed; the nucleic acids are recovered, concentrated, and purified. The invention also relates to a filtering cartridge and an apparatus used for carrying out the inventive extraction method. Also disclosed is a device for extracting, detecting, and if necessary quantifying the nucleic acids of microorganisms contained in a complex mixture.

  • Publication number: 20040081987
    Abstract: The present invention is directed to a device and a method for detecting biomolecules in a tissue section or other two-dimensional sample by creating “carbon copies” of the biomolecules eluted from the sample and visualizing the biomolecules on the copies using antibodies or DNA probes having specific affinity for the biomolecules of interest. Thin membranes in a stacked or layered configuration are applied to the sample, such as a tissue section, and reagents and reaction conditions are provided so that the biomolecules are eluted from the sample and transferred onto each of the stacked membranes thereby producing multiple replicas of the biomolecular content of the sample.
