Abstract:
A device for controlling temperature in a reaction chamber is disclosed. The device comprises: a bladder assembly comprising a housing dimensioned to hold a reaction chamber disposed within an interior volume of the housing; and a first temperature-control bladder disposed within the housing, the first temperature-control bladder is configured to receive a temperature-control fluid and comprises a flexible, heat conductive surface that comes in contact with at least a portion of an exterior surface of the reaction chamber after receiving the temperature-control fluid. Also disclosed are a bladder thermal cycler, a temperature-control bladder assembly and methods for producing a thermal cycle in a reaction chamber.
Abstract:
Methods and devices for performing chemical reactions under controlled temperatures are described. In one embodiment, the devices provided by the invention comprise a housing dimensioned to hold a reaction chamber disposed within an interior volume of the housing. The reaction chamber has thermally conductive interior and exterior surfaces defining an internal volume therein at a first temperature. The device also includes at least one thermally conductive temperature-control bladder disposed therein, which bladder is configured to receive a temperature-control substance at a second temperature into said bladder and expel said temperature-control substance from said bladder. The bladder is further configured such that upon receiving the temperature-control substance, the bladder expands to abut substantially at least a portion of said exterior surfaces of said reaction chamber to enable thermal exchange between said temperature-control substance the said internal volume of reaction chamber.
Abstract:
Provided herein are improved methods, compositions, and kits for analysis of nucleic acids. The improved methods, compositions, and kits can enable copy number estimation of a nucleic acid in a sample. Also provided herein are methods, compositions, and kits for determining the linkage of two or more copies of a target nucleic acid in a sample (e.g., whether the two or more copies are on the same chromosome or different chromosomes) or for phasing alleles.
Abstract:
A sample collection system and method for airborne biological agents is disclosed. The sample collection system comprises a sample collection module that collects particles in an air flow and transfer the collected particles into a sampling fluid, and a sample preparation module that is responsible for accepting the sampling fluid from the sample collection module, continuously aggregating or concentrating the collected particles in the sampling fluid during the sampling process and recycling a particle-lean sampling fluid back to the collection module.
Abstract:
A sample preparation device is disclosed. The sample preparation device includes a housing defining a passage way between a first opening and a second opening; and a sample filter occupying a section of said passage way. The sample filter contains a monolith adsorbent that specifically binds to nucleic acids. Also disclosed are sample filters containing glass frit is coated with an capture agent that binds specifically to an analyte of interest, sample filters containing a hydrophilic matrix with impregnated chemicals that lyses cell membranes, a cartridge base and an integrated sample preparation cartridge.
