DESCRIPTION (provided by applicant): We will develop optimized methods for the enzymatic production of modified oligonucleotides which have strong advantages as therapeutic agents and biosensors. We will first implement a Sequential Injection Analysis (SIA) platform with continuous data collection to optimize biochemical protocols with large parameter spaces. We will use this platform to optimize conditions for in vitro transcription of 2'-O-methyl and 2'-fluoro RNA. We will also implement a continuous, continuous- or semi-continuous-flow bioreactor for in vitro production of modified RNA for use in ongoing projects including microfluidic cancer cell capture and in vivo evaluations of aptamer therapeutics. Microreactors of the type we will build have been demonstrated for controlled, efficient, scalable, synthetic organic chemistry. These same advantages make the strategy attractive for biochemical reactions. PUBLIC HEALTH RELEVANCE: Chemically modified DNA and RNA are more resistant to being destroyed by the environment in blood, and so they are preferred as tools to develop drugs or instruments used for clinical testing. Current methods for generating these valuable substances are very expensive and produce very little of the product, which limits their use. This project will develop an improved method to generate modified DNA and RNA which will allow wider use of these important chemical tools.

描述(申请人提供)：我们将开发优化的方法，以酶法生产具有强大优势的修饰寡核苷酸作为治疗剂和生物传感器。我们将首先实现一个连续数据收集的顺序注入分析(SIA)平台，以优化具有大参数空间的生化方案。我们将利用这个平台来优化2‘-O-甲基和2’-氟RNA的体外转录条件。我们还将实施一种连续、连续或半连续流动的生物反应器，用于体外生产修饰的RNA，用于正在进行的项目，包括微流控癌细胞捕获和适体治疗药物的体内评估。我们将建造的这种类型的微反应器已经被证明是可控的、高效的、可扩展的、合成有机化学的。这些同样的优势使该策略对生化反应具有吸引力。 公共卫生相关性：化学修饰的DNA和RNA更不易被血液中的环境破坏，因此它们被用作开发用于临床测试的药物或仪器的首选工具。目前生产这些有价值物质的方法非常昂贵，而且生产的产品很少，这限制了它们的使用。该项目将开发一种改进的方法来产生修饰的DNA和RNA，这将使这些重要的化学工具得到更广泛的使用。
