Equipment for Affinity Foam Separations and Protein Adsorption Studies

这是一项购买设备的建议，以加强美国国家科学基金会赞助的生物分子亲和泡沫分离研究和气液界面蛋白质吸收研究。所要求的紫外记录分光光度计将用于测量蛋白质混合物的光谱和进行动力学分析。朗缪尔膜天平将能够同时测量表面压力和过量表面浓度。要求升级现有的Perkin-Elmer等梯度折射率检测器高效液相色谱系统，将使蛋白质混合物的凝胶渗透高效液相分析成为可能。建议提供为期12个月的赠款，金额为52,067美元，全部来自87财年基金。

This is a proposal for the purchase of equipment to enhance NSF- sponsored research on affinity foam separations of biomolecules and protein absorption studies at gas-liquid interfaces. The requested UV recording spectrophotometer will be used for measuring the spectra of protein mixtures and in performing kinetic assays. The Langmuir film balance will enable simultaneous measurements of surface pressure and excess surface concentration. The requested upgrade of an existing Perkin-Elmer isocratic, refractive-index detector HPLC system will enable the gel permeation HPLC analysis of protein mixtures. A 12-month grant is recommended in the amount of $52,067, all from FY87 funds.
