  • Publication number: 20150344973
    Abstract: The invention provides, inter alia, systems, compositions, kits and methods for detecting an organism, such as a microbe, microorganism, pathogen, or organism associated with Hospital Associated Infections (HAIs). The systems, compositions, kits and methods can comprise one or more probes for detecting a strain with high sensitivity, high specificity, or both. The systems, compositions, kits and methods can also be used to detect the strain within a short time frame.

  • Publication number: 20090144270
    Abstract: A method of matching candidates with a user based upon, in part, on genetic factors including the following steps. First, a database is maintained including one or more of candidates having personal profiles. Next, a personal profile of a user is compared with the personal profiles of the candidates in the database for purposes of social compatibility. A set of candidates is generated which are socially compatible with the user. The personal profile of the user is then compared with each of the personal profiles of the generated set of candidates. The risk of the user producing offspring having a disease with each of the candidates within the generated set is determined. Finally, a user is presented with the set of candidates along with the determination of the risk of the user and selected candidate producing offspring having a disease.

  • Patent number: 7297534
    Abstract: A process for the recovery of plasmids or other DNA from cells using a first filtration step to remove the cellular debris and other large cellular components and then an ultrafiltration step to capture the plasmids or other DNA on the surface of the ultrafiltration membrane where they may be recovered. An apparatus is also taught for enacting the process and comprises an upper microfiltration or coarse filtration membrane and a lower ultrafiltration membrane. The driving force may be the same for both filters or different and may be done sequentially or simultaneously.

  • Publication number: 20030036086
    Abstract: A system for holding a multiple welled plate during processing comprised of a multiple welled plate, typically containing 96, 384 or more individual wells, each having an open bottom closed by a membrane and a holder for such a plate. The holder is formed with a filter support portion that supports the lower surface of the filter during processing. The holder may optionally be thermally conductive or if not thermally conductive, may include an additional thermally conductive layer between the lowermost surface of the filter and the filter support portion to provide for thermal cycling applications.
