项目摘要

DESCRIPTION: Life sciences research and other critical bioanalytical applications would strongly benefit from faster and higher resolution liquid chromatographic (HPLC) separations for both small molecules and larger molecules such as proteins, peptides, glycopeptides, and glycans. Many HPLC separations of biomedical interest, such as proteomic or glycomic profiling, require hours or days for resolution of a single sample. Due to the complexity of biological samples, there are many examples in the current research literature that combine multiple dimensions of HPLC separations, often with online mass spectroscopy (MS). Although very time consuming, this approach has yielded useful information on protein expression and post-translational modifications, the biological processes underlying protein expression and modifications, and the effects thereon of development, disease state, and various environmental and genetic factors. In various complex bioanalytical workflows, high efficiency LC separations are a fundamental part of the analytical systems, and the time to achieve high resolution separations of complex biological samples is a great bottleneck. This proposal describes an approach to improve the separation efficiency of HPLC by extending our proprietary Fused-Core silica platform technology to non-spherical superficially porous particals, including ellipsoids, providing significantly faster and higher resolution separations. Our objectives are to create 2.5-5 ?m diameter ellipsoidal superficially porous Fused-Core silica particles, and to load these materials efficiently into HPLC column formats. The goals of the proposed work could yield very high performance chromatographic products, greater than those currently available, to be applied broadly in analysis of complex biological samples, pharmaceutical and biopharmaceutical applications, in fact in any current application that uses HPLC methods. The separations technology described will directly lead to useful products for which there is a significant technical and market demand.

产品说明：生命科学研究和其他关键的生物分析应用将大大受益于更快和更高分辨率的液相色谱（HPLC）分离小分子和大分子，如蛋白质、肽、糖肽和聚糖。许多具有生物医学意义的HPLC分离，如蛋白质组学或糖组学分析，需要数小时或数天才能解析单个样品。由于生物样品的复杂性，在当前的研究文献中有许多实例将联合收割机的多个维度的HPLC分离（通常与在线质谱（MS））相结合。虽然非常耗时，但这种方法已经产生了关于蛋白质表达和翻译后修饰、蛋白质表达和修饰的生物学过程以及发育、疾病状态和各种环境和遗传因素对蛋白质表达和修饰的影响的有用信息。在各种复杂的生物分析工作流程中，高效LC分离是分析系统的基本部分，实现复杂生物样品的高分辨率分离的时间是一个很大的瓶颈。该提案描述了一种提高HPLC分离效率的方法，方法是将我们专有的熔核二氧化硅平台技术扩展到非球形表面多孔颗粒（包括椭球体），从而提供更快和更高的分辨率分离。我们的目标是创造2.5-5？m直径的椭圆形表面多孔的熔核二氧化硅颗粒，并将这些材料有效地装载到HPLC柱形式中。所提出的工作的目标可以产生非常高的性能色谱产品，大于目前可用的，被广泛应用于复杂的生物样品，制药和生物制药应用的分析，事实上，在任何当前的应用，使用HPLC方法。所描述的分离技术将直接导致有用的产品，对于这些产品存在显著的技术和市场需求。
