Abstract: The present invention provides methods, compositions, and kits for performing amplification (e.g., whole genome amplification) employing primers that have a 5? restriction site, a 3? random sequence (e.g., a random hexamer), and an identifiable barcode sequence. In certain embodiments, the amplification generates individual amplified sequenced that are ligated together to form concatamers containing at least two amplified sequences (e.g., not contiguous on the original target sequence) that are separated by the barcode sequences. In particular embodiments, a plurality of the concatamers are sequenced and aligned with an alignment algorithm that uses the barcode sequences to identify artificial junctions between amplified sequences.

Abstract: The present invention provides systems, methods, and compositions for nucleic acid detection based on non-mass determined base compositions. For example, in certain embodiments, base count data for a template nucleic acid is generated using an approach that does not measure molecular mass of the template nucleic acid (e.g., by sequencing the template nucleic acid) and a database comprising base count entries is queried to identify the target nucleic acid. In particular embodiments, sequencing is employed which is conducted in substantially real-time.

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.

Abstract: Cartridges useful for mixing materials, such as fluidic materials are provided. A cartridge typically includes a body structure having surfaces that define a cavity with upper and lower portions. A rotatable member generally extends along a horizontal axis in the upper portion of the cavity. One or more protrusions typically extend outward from the rotatable member and into the lower portion of the cavity, and are configured to mix the material when the material is disposed in the cavity. Related mixing stations, systems, kits, and methods are also provided.

Such enzyme mixtures may be lyophilized and stored at room temperature without significant loss of enzyme activity for months.
