  • Publication number: 20170091085
    Abstract: Aspects include testing distributed file systems by selecting a file in a multiple writer environment and selecting an offset of a block in the file. Test data is generated for the block by randomly selecting a starting value from a plurality of possible starting values. A test header that includes the starting value and a test data sequence that starts with the starting value is created. A file system that is being tested writes the test header and the test data sequence to the block. Contents of the block are read by the file system that is being tested, and expected contents of the data sequence are determined based on contents of the read header. The expected contents of the data sequence are compared to the read data sequence and an error indication is output based on the expected contents not being equal to the read contents.

  • Publication number: 20140065689
    Abstract: The invention provides compositions and methods for storage of biomolecules. The biomolecules are stored via absorption to a substrate. Absorbed biomolecules can be eluted or recovered from the substrate at a future time, and optionally be subjected to a subsequent analysis or application. Biomolecules absorbed to a substrate for storage may also optionally be preserved, i.e., the absorbed biomolecule is resistant to or resists degradation.

  • Patent number: 7776401
    Abstract: A process of treating a woven fabric by applying to the fabric a viscous polymer in a 5 to 40 wt % solution with a solvent, wherein the polymer has a Tg in the range of about minus 40 to about 0° C. and a zero shear melt viscosity of about 2×106 to about 1013 poise when measured at 20° C. and then evaporating the solvent such that the polymer only partially penetrates the fabric and penetrates to in and between fiber bundles before the polymer solidifies.

  • Publication number: 20100173392
    Abstract: The present invention provides compositions and methods for efficient recovery of nucleic acids, in particular DNA, from storage media. The present invention provides a method for using an alkaline elution buffer and mechanical agitation to elute nucleic acids from dried samples on storage media at room temperature. In particular, the present invention provides a method for room temperature recovery of DNA, including double stranded DNA (dsDNA) and single stranded (ssDNA), from storage media.

  • Patent number: 7718442
    Abstract: A system and method operative in accordance with the present disclosure facilitate storage and retrieval of individual or discrete samples of biological, non-biological, and chemical material stored on dry media. Sample material may be disposed upon or within a porous or solid (i.e., non-porous) sample storage medium and subsequently archived in, and retrieved from, storage elements such as multi-well plates, for example, using robotic devices or other automated apparatus. The disclosed system and method enable ejection of sample material from a sealed storage element into a specific well of a multi-well daughter plate, or into a specific cuvette, test tube, or similar container. In some embodiments, a sample carrier comprising a storage medium may be punched or ejected through a first seal of the storage element with an apparatus or implement such as a disposable piercing tip, for instance, inserted through a second seal of the storage element.

  • Publication number: 20090043087
    Abstract: This invention relates to methods for rapid nucleic acid purification from sources heavily contaminated with high particulate material, such as cellular debris, and solids, including suspended solids. In particular, this invention provides methods for rapid, quantifiable recovery and purification of nucleic acids from a variety of sources heavily contaminated with solids, such as small organisms, tissue samples, samples of blood found on soil, or samples of washing from foods, which are frequently difficult sources for nucleic acid isolation due to their propensity to clog filters and columns. A device and kit are also provided.

  • Patent number: 6645717
    Abstract: A medium for storage and subsequent analysis of a genetic material includes a support for immobilizing the genetic material thereon and allowing subsequent elution of the genetic material therefrom and a coating functionally associated with the support for enabling cellular lysis and releasing the genetic material from the lysed cells while stabilizing the immobilized released genetic material. A method of storing the genetic material and subsequently analyzing the genetic material includes the steps of immobilizing the genetic material on a support while enabling cellular lysis and release of genetic material from the lysed cells and stabilizing the immobilized released genetic material on the support. The genetic material is then eluted to generate a soluble genetic material fraction. The eluted genetic material can be analyzed.
