  • Patent number: 8921047
    Abstract: The present invention relates generally to the field of investigational bioinformatics and more particularly to secondary structure defining databases. The present invention further relates to methods for interrogating a database as a source of molecular masses of known bioagents for comparing against the molecular mass of an unknown or selected bioagent to determine either the identity of the selected bioagent, and/or to determine the origin of the selected bioagent. The identification of the bioagent is important for determining a proper course of treatment and/or irradication of the bioagent in such cases as biological warfare. Furthermore, the determination of the geographic origin of a selected bioagent will facilitate the identification of potential criminal identity.

  • Patent number: 8609430
    Abstract: Sample processing units useful for mixing and purifying materials, such as fluidic materials are provided. A sample processing unit typically includes a container configured to contain a sample comprising magnetically responsive particles, and one or more magnets that are in substantially fixed positions relative to the container. A sample processing unit also generally includes a conveyance mechanism configured to convey the container to and from a position that is within magnetic communication with the magnet, e.g., such that magnetically responsive particles with captured analytes can be retained within the container when other materials are added to and/or removed from the container. Further, a sample processing unit also typically includes a rotational mechanism that is configured to rotate the container, e.g., to effect mixing of sample materials disposed within the container. Related carrier mechanisms, sample processing stations, systems, and methods are also provided.

  • Patent number: 8551738
    Abstract: There is a need for nucleic acid analysis which is both specific and rapid, and in which no nucleic acid sequencing is required. The present invention addresses this need, among others by providing a method of nucleic acid amplification of overlapping sub-segments of a nucleic acid followed by molecular mass measurement of resulting amplification products by mass spectrometry, and determination of the base compositions of the amplification products.
