MRI: Acquisition of an Isothermal Titration Calorimeter

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。通过这项来自主要研究仪器（MRI）项目的奖励，纽约州立大学波茨坦分校的Fadi boub - abdallah教授将获得一台等温滴定量热计。它将支持波茨坦以及附近的圣劳伦斯和克拉克森大学的同事们的研究。主要的研究将包括：1)阐明转铁蛋白如何与其特异性受体相互作用，从而使铁有效地传递到细胞；2)室温离子液体（RTILs）中酶行为的热力学表征；3)神经元特异性烯醇酶（NSE）与抗NSE抗体之间热力学相互作用的表征；4)与谷胱甘肽活性络合基团的重金属离子螯合物的研究。5)确定调控酶Rubisco激活酶（RA）的两种同工异构体与Rubisco结合的化学计量学和这些结合事件的热力学表征；6)确定诺加霉素与DNA结合的热力学。等温滴定量热法（ITC）是一种非常灵敏的热力学技术，用于表征物质（如小分子）与酶之间的结合相互作用。ITC直接测量结合反应中吸收或释放的热量。这提供了对化学和生化结合相互作用强度的见解。这一工具将用于三个合作机构的本科生的研究，并提供给该区域的其他机构。它将被纳入几个高年级的实验课。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).Through this award from the Major Research Instrumentation (MRI) program, Professor Fadi Bou-Abdallah at SUNY Potsdam will acquire an isothermal titration calorimeter. It will support the research of colleagues at Potsdam, and nearby St Lawrence and Clarkson Universities. The primary research studies will include, 1) elucidation of how transferrin interacts with its specific receptor to bring about the efficient delivery of iron to cells, 2) thermodynamic characterization of enzyme behavior in room temperature ionic liquids (RTILs), 3) characterization of the thermodynamic interactions between neuron specific enolase (NSE) and anti-NSE antibody, 4) studies of heavy metal ion chelates with glutathione active complexing groups, 5) determination of the binding stoichiometry of two isoforms of the regulatory enzyme Rubisco Activase (RA) with Rubisco and thermodynamic characterization of these binding events, and 6) determination of the thermodynamics of nogalamycin binding to DNA.Isothermal titration calorimetry (ITC) is a very sensitive thermodynamic technique that is used to characterize binding interactions between species such as a small molecule to an enzyme. ITC measures directly the heat absorbed or released during a binding reaction. This provides insight on the strength of chemical and biochemical binding interactions. This instrument will be used in research by undergraduates at the three collaborating institutions and made available to other institutions in the region. It will be incorporated into several upper division level laboratory classes.
