  • Patent number: 7328628
    Abstract: The invention, in various embodiments, provides systems, methods and devices relating to processing a sample. A vessel is described for containing a sample. The vessel includes a reversibly sealable chamber for containing the sample which has a flexible portion to allow the vessel to deform nondestructively in response to a mechanical impact to fragment the sample. In certain embodiments the vessel may include a port for reversibly engaging with a second vessel to enable transfer of material between the two vessels while maintaining a barrier between the sample and an external environment. The vessel may be exposed to mechanical impacts of various energies and at various temperatures, and the internal surface of the structural barrier of the vessel may be treated with various chemical agents to maintain integrity of the sample.

  • Publication number: 20070014690
    Abstract: Devices and methods are described for homogenization, processing, detection, and analysis of biological samples such as insects, fungi, bacteria, and plant and animal tissues. Multiple chambers in these devices permit different processing functions to be carried out at each stage, such that the resulting homogenized product can be further processed, purified, analyzed, and/or biomolecules such as metabolites, proteins and nucleic acids, or pharmaceutical products can be detected. The device can be used in a hydrostatic pressure apparatus, in which different activities, i.e. incubations, addition or renewal of reagent, and generation and detection of signal can be carried out in the appropriate chamber. The method improves the preservation of biomolecules from chemical and enzymatic degradation relative to conventional means. Additionally, this method enables automated sample preparation and analytical processes.

  • Publication number: 20040151620
    Abstract: The invention is based on the discovery that biological and non-biological materials can be sterilized, decontaminated, or disinfected by repeatedly cycling between relatively high and low pressures. Pressure cycling can be carried out at low, ambient, or elevated temperatures (e.g., from about −40° C. to about 95° C., or intermediate ranges). New methods based on this discovery can have applications in, for example, the preparation of vaccines, the sterilization of blood plasma or serum, plant, animal, and human tissue, sputum, urine, feces, water, and ascites, the decontamination of military devices, food and beverage production, and the disinfection of medical equipment. The new methods can also be incorporated into production processes or research procedures.

  • Patent number: 6635469
    Abstract: The invention relates to (1) pressure-mediated dissociation of an analyte complexed with an endogenous binding partner to enable detection of a complex formed from the analyte and an exogenous binding factor, (2) pressure-mediated association of an analyte and an exogenous binding partner to enable more rapid and/or more sensitive detection of an analyte, and (3) pressure-mediated association and dissociation of biomolecular complexes to enable separation of one biomolecule from a complex mixture. Pressure can be used to improve assays by dissociating endogenous analyte complexes and improving assay speed and sensitivity by associating the analyte molecules with exogenously supplied binding partners. Pressure can also be used to improve the separation of compounds from contaminated mixtures.

  • Patent number: 6448065
    Abstract: The invention is based on the discovery that the sequence of monomers in a polymeric biomolecule can be determined in a self-contained, high pressure reaction and detection apparatus, without the need for fluid flow into or out from the apparatus. The pressure is used to control the activity of enzymes that digest the polymeric biomolecule to yield the individual monomers in the sequence in which they existed in the polymer. High pressures modulate enzyme kinetics by reversibly inhibiting those enzymatic processes which result in a higher average activation volume, when compared to the ground state, and reversibly accelerating those processes which have lower activation volumes than the ground state. Modulating the pressure allows the experimenter to precisely control the activity of the enzyme. Conditions can be found, for example, where the enzyme removes only one monomer (e.g., a nucleotide or amino acid) from the biomolecule before the pressure is again raised to a prohibitive level.
