DESCRIPTION (provided by applicant): Real-time PCR and real-time reverse transcriptase PCR assays are highly specific for determining the presence of pathogens. However these assays are traditionally confined to the laboratory as result of the need for trained technicians to perform key steps in the process, particularly sample preparation, as well as cost and size of equipment to run these assays. New equipment platforms are needed to allow these sensitive and highly selective assays to be used in non-traditional settings such as a doctor's office and nursing homes. Lynntech proposes an innovative, easy-to-operate system that automates well-established sample preparation protocols for nucleic acid extraction and purification with a novel microfluidic thermocycler to perform real-time PCR on disposable analysis cartridges for determination of pathogens in biological samples. Fluid control is achieved on-cartridge through use of low cost components (<$0.60 per component). The PCR based system provides random access nucleic acid testing in one hour, from nucleic acid extraction and purification to amplification and real-time detection. The technology is anticipated to be able to detect a broad range of pathogens at a level between 102 to 103 units per milliliter. The system's random-access nucleic acid analysis capability allows for samples to be run whenever needed. The implementation of the system will significantly reduce diagnostic lead times. Also, important is the simplicity of the system which leads to low-cost systems. Lynntech's real-time PCR system is a next generation tool for molecular diagnostics that will enable non- specialized operators in non-traditional settings (e.g., nurse at doctor's office or nursing home) to perform sophisticated biological tests in any setting with greater speed at low cost. The automation provided in this system significantly simplifies and accelerates testing, thus delivering molecular diagnostics into the hands of health-care professionals (i.e., doctors and nurses). The system will be a great resource for poor communities and countries where traditional tests are not available or are cost prohibitive. PUBLIC HEALTH RELEVANCE: The technology provides needed simplification and automation to nucleic acid based diagnostic assays to bring them out of the laboratory and into non-traditional environments. The system will have great commercial potential and medical value in providing rapid, low-cost, easy-to-use in vitro diagnostics in doctors' offices, clinics, hospitals, and even in poor communities and countries.

描述（由申请方提供）：实时PCR和实时逆转录酶PCR检测对于确定是否存在病原体具有高度特异性。然而，由于需要训练有素的技术人员来执行过程中的关键步骤，特别是样品制备，以及运行这些测定的设备的成本和尺寸，这些测定传统上局限于实验室。需要新的设备平台来允许这些敏感和高选择性的测定在非传统环境中使用，例如医生办公室和疗养院。Lynntech提出了一种创新的、易于操作的系统，该系统使用新型微流体热循环仪自动化完善的核酸提取和纯化样品制备方案，在一次性分析盒上进行实时PCR，以确定生物样品中的病原体。通过使用低成本组件（每个组件<0.60美元），在墨盒上实现流体控制。基于PCR的系统在一小时内提供随机访问核酸检测，从核酸提取和纯化到扩增和实时检测。该技术预计能够检测到每毫升102至103单位的各种病原体。该系统的随机存取核酸分析能力允许在需要时运行样本。该系统的实施将大大缩短诊断准备时间。此外，重要的是系统的简单性，这导致低成本系统。Lynntech的实时PCR系统是用于分子诊断的下一代工具，其将使非专业操作员能够在非传统环境中（例如，医生办公室或疗养院的护士）在任何环境中以更快的速度和更低的成本进行复杂的生物测试。该系统提供的自动化显着简化和加速了测试，从而将分子诊断交付给医疗保健专业人员（即，医生和护士）。该系统将成为贫困社区和国家的一个重要资源，因为那里没有传统的测试或成本过高。公共卫生关系：该技术为基于核酸的诊断测定提供了所需的简化和自动化，以将它们带出实验室并进入非传统环境。该系统将具有巨大的商业潜力和医疗价值，可为医生办公室、诊所、医院，甚至贫困社区和国家提供快速、低成本、易于使用的体外诊断。
