Abstract: Nucleic acid from cells and viruses sampled from a variety of environments may purified and expressed utilizing microfluidic techniques. Individual or small groups of cells or viruses may be isolated in microfluidic chambers by dilution, sorting, and/or segmentation. The isolated cells or viruses may be lysed directly in the microfluidic chamber, and the resulting nucleic acid purified by exposure to affinity beads. Subsequent elution of the purified nucleic acid may be followed by ligation and cell transformation, all within the same microfluidic chip. Cell isolation, lysis, and nucleic acid purification may be performed utilizing a highly parallelized microfluidic architecture to construct gDNA and cDNA libraries.

Abstract: A fluid valve is provided that includes a first planar substrate having a smooth surface or a surface with features, an elastomer disposed on the first substrate, a second planar substrate disposed on another side of the elastomer, where the second substrate has a smooth surface or features, where the first and second substrate are more rigid than the elastomer, where the first substrate, the second substrate or the elastomer has a fluid channel, where the channel is open when the first or second substrate are in a first thermal state or a first compression state, where the channel is closed or partially closed when the first or second substrate are in a second thermal state or a second compression state, where the second thermal state is a different temperature than the first thermal state, where the second compression state is a different pressure than the first compression state.

Abstract: The present invention provides microfluidic devices and methods for using the same. In particular, microfluidic devices of the present invention are useful in conducting a variety of assays and high throughput screening. Microfluidic devices of the present invention include elastomeric components and comprise a main flow channel; a plurality of branch flow channels; a plurality of control channels; and a plurality of valves. Preferably, each of the valves comprises one of the control channels and an elastomeric segment that is deflectable into or retractable from the main or branch flow channel upon which the valve operates in response to an actuation force applied to the control channel.

Abstract: The invention generally relates to methods for assessing the health of a tissue by characterizing circulating nucleic acids in a biological sample. According to certain embodiments, methods for assessing the health of a tissue include the steps of detecting a sample level of RNA in a biological sample, comparing the sample level of RNA to a reference level of RNA specific to the tissue, determining whether a difference exists between the sample level and the reference level, and characterizing the tissue as abnormal if a difference is detected.

Abstract: Herpes simplex virus (HSV) including herpes simplex virus 1 and 2 (HSV-1 and HSV-2) are a persistent cause of human disease with no known cure. Guided nuclease systems target specific regions of the HSV-1 and HSV-2 genomes, disrupting the virus' nucleic acid and rendering even latent viruses incapacitated.

Abstract: The invention provides compositions and methods for treating human papillomavirus (HPV) infections using a targetable nuclease, which compositions and methods can be used to selectively target the HPV genome or selectively express the targetable nuclease within cells that infected by HPV. By selectively targeting cells infected by HPV, the HPV genome within infected cells, or both, the nuclease is able to cleave the HPV genome thereby inactivating it and rendering it inoperable, interfering with the virus's ability to propagate even where the virus is in a latent stage of infection. Since latent HPV can be cleaved and eradicated from the host cells, compositions and methods of the invention may be used to treat HPV infections and potentially prevent many of the adverse health consequences associated with the papillomavirus.

Abstract: Nucleic acid from cells and viruses sampled from a variety of environments may purified and expressed utilizing microfluidic techniques. In accordance with one embodiment of the present invention, individual or small groups of cells or viruses may be isolated in microfluidic chambers by dilution, sorting, and/or segmentation. The isolated cells or viruses may be lysed directly in the microfluidic chamber, and the resulting nucleic acid purified by exposure to affinity beads. Subsequent elution of the purified nucleic acid may be followed by ligation and cell transformation, all within the same microfluidic chip. In one specific application, cell isolation, lysis, and nucleic acid purification may be performed utilizing a highly parallelized microfluidic architecture to construct gDNA and cDNA libraries.

Abstract: The invention provides delivery methods and compositions for antiviral therapeutics. Methods and compositions are provided for targeted delivery of antiviral therapeutics into cells of interest using, for example, viral vectors such as adenovirus, AAV, and replication incompetent HSV. These and other delivery systems can be used as vehicles to deliver DNA vectors encoding a nuclease or a cell-killing gene. These delivery methods can also be used to deliver naked DNA or RNA, protein products, plasmids containing a promoter that is active only in a latent viral state which drives a cell-killing gene, or other therapeutic agents.
