The present disclosure provides systems and methods for sample preparation, processing and analysis. Also provided in the present disclosure is a fully-integrated electrophoresis cartridge which has a small footprint and configured to removably engage with the system. An electrophoresis cartridge adapted to releasably engage with a cartridge interface of a system is provided. The electrophoresis cartridge (500) comprises: an electrophoresis assembly including: (1) an anode sub-assembly (507) comprising an anode (559), (2) a cathode sub-assembly (510) comprising a cathode (511); and (3) at least one electrophoresis capillary (509) having a first end and a second end, wherein the cathode (511) and the anode (529) are configured to provide a voltage gradient across the first end and the second end of the at least one electrophoresis capillary (509).
摘要:
The invention provides systems, devices, methods, and kits for performing an integrated analysis. The integrated analysis can include sample processing, library construction, amplification, and sequencing. The integrated analysis can be performed within one or more modules that are fluidically connected to each other. The one or more modules can be controlled and/or automated by a computer. The integrated analysis can be performed on a tissue sample, a clinical sample, or an environmental sample. The integrated analysis system can have a compact format and return results within a designated period of time.
摘要:
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 ft 3 , 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.
