项目摘要
DESCRIPTION (provided by applicant): This shared instrumentation grant program proposal requests funds for the purchase of a state-of-the-art isothermal titration microcalorimeter (ITC). Calorimetry provides a wealth of information about macromolecular interactions and enzymatic kinetics by measuring the heats of reaction. This technique has distinct advantages over others, including that it can obtain information about the binding affinity, enthalpy and entropy of reaction and stoichiometry of the reaction in a single experiment and that it does not require the labeling of either the titrant or titrate molecules. Recent advances in instrumentation also allow for 10-fold lower sample amounts to be used per experiment and significantly decreased run time as compared to previous generation instruments. These considerations make this technique accessible to a broader spectrum of users and facilitates overall higher throughput, which are important features for shared instrumentation. Acquisition of the proposed MicroCal iTC200 would facilitate research programs directly related to human health issues in a number of important ways. Major users of this instrument propose to use this instrument to investigate the regulatory mechanisms of kinases involved in a variety of key cellular signal transduction pathways in humans (Prof. Natalie Ahn), RNA-based regulatory elements that directly sense cellular metabolites (Prof. Robert Batey), a nucleic acid aptamer that is an FDA- approved drug to fight macular degeneration (Prof. Arthur Pardi), and the nature of protein-DNA interactions at the end of linear chromosomes (Prof. Deborah Wuttke). These research goals along with those of the minor users emphasizes the strength of biophysics and biochemistry at the University of Colorado, Boulder and the proposed instrument would fulfill a core need of a large community of users.
描述(由申请人提供):这个共享仪器补助金计划提案要求资金购买一个国家的最先进的等温滴定微量热计(ITC)。量热法通过测量反应热提供了大量关于大分子相互作用和酶动力学的信息。这种技术具有明显的优势,包括它可以获得有关的结合亲和力,焓和熵的反应和化学计量的反应在一个单一的实验,它不需要标记的滴定剂或滴定分子。与上一代仪器相比,仪器的最新进展还允许每次实验使用的样品量降低10倍,运行时间显著缩短。这些考虑因素使得更广泛的用户可以使用这种技术,并促进整体更高的吞吐量,这是共享检测的重要特性。收购拟议的MicroCal iTC 200将在许多重要方面促进与人类健康问题直接相关的研究计划。该仪器的主要用户建议使用该仪器来研究人类多种关键细胞信号转导途径中所涉及的激酶的调节机制(Natalie Ahn教授),直接感知细胞代谢物的RNA调控元件(Robert Batey教授),一种核酸适体,是FDA批准的对抗黄斑变性的药物(亚瑟帕迪教授),以及线性染色体末端蛋白质-DNA相互作用的性质(黛博拉·伍特克教授)。这些研究目标沿着那些未成年用户的研究目标,强调了博尔德市科罗拉多大学生物物理学和生物化学的优势,并且所提出的仪器将满足大型用户社区的核心需求。
