Abstract:
This disclosure provides an integrated and automated sample-to-answer system that, starting from a sample comprising biological material, generates a genetic profile in less than two hours. In certain embodiments, the biological material is DNA and the genetic profile involves determining alleles at one or a plurality of loci (e.g., genetic loci) of a subject, for example, an STR (short tandem repeat) profile, for example as used in the CODIS system. The system can perform several operations, including (a) extraction and isolation of nucleic acid; (b) amplification of nucleotide sequences at selected loci (e.g., genetic loci); and (c) detection and analysis of amplification product. These operations can be carried out in a system that comprises several integrated modules, including an analyte preparation module; a detection and analysis module and a control module.
Abstract:
The invention provides a system that can process a raw biological sample, perform a biochemical reaction and provide an analysis readout. For example, the system can extract DNA from a swab, amplify STR loci from the DNA, and analyze the amplified loci and STR markers in the sample. The system integrates these functions by using microfluidic components to connect what can be macrofluidic functions. In one embodiment the system includes a sample purification module, a reaction module, a post-reaction clean-up module, a capillary electrophoresis module and a computer. In certain embodiments, the system includes a disposable cartridge for performing analyte capture. The cartridge can comprise a fluidic manifold having macrofluidic chambers mated with microfluidic chips that route the liquids between chambers. The system fits within an enclosure of no more than 10 ft3. and can be a closed, portable, and/or a battery operated system. The system can be used to go from raw sample to analysis in less than 4 hours.
Abstract:
The disclosure provides methods and devices for separating and detecting nucleic acid fragments labeled with a plurality of spectrally resolvable dyes using a single light source or multiple light sources. Use of a greater number of light sources increases the number of spectrally resolvable dyes that can be interrogated. Labeling fragments with a greater number of spectrally resolvable dyes permits more overlapping of fragments with differentiation of the fragments, and thus separation can be conducted on a smaller range of fragment sizes/lengths. To improve the detection sensitivity of a detection system employing multiple light sources, light emitted by the light sources can be spatially separated from one another and/or the intensity of each of the light sources can be modulated. Each of the one or more light sources can be, e.g., a laser or a light-emitting diode. The methods and devices of the disclosure are useful for performing genetic analysis, e.g., analysis of a plurality of STR markers utilized in a forensic database (e.g., CODIS) to identify humans.
Abstract:
The present technology relates to pins that are used for moving liquid samples from source wells into target wells. A releasable fastening mechanism simplifies calibration of positions (e.g., vertical positions) of the pins relative to a frame releasably holding the pins.

Abstract:
A system for controlling custody of a sample can include a cartridge comprising a sample receptacle configured to receive an article configured to deliver a sample to the cartridge, a cartridge module having a cartridge receptacle configured to receive the cartridge; a housing enclosing the cartridge module and the cartridge. The housing can include a closable door; at least one sensor configured to produce a signal indicating: insertion or removal of an article into or from the sample receptacle; whether the cartridge is inserted into the cartridge receptacle; or whether the door is open or closed. The system can further include a computer programmed to record a signal from the at least one sensor for a recording period of time and to display a signal history to a user.
