Administrative supplement application for equipment purchase

补充摘要 设备采购行政补充申请 这是购买AKTA_Pure Fast Pressure Liquid的行政补充申请 来自Cytiva的色谱（FPLC）系统。AKTA_Pure FPLC是一种中等流量、中等压力 色谱系统，允许半自动化，快速和高分辨率的色谱分析， 通过离子交换、疏水相互作用、凝胶过滤和亲和层析分离蛋白质。 通过FPLC实现的蛋白质纯化和分析是所有生物技术的核心和不可或缺的要求。 作为我的NIGMS资助的R35/MIRA奖的一部分，我的实验室正在进行一些项目。全新AKTA_Pure 本补充中要求的FPLC将直接替换故障AKTA_Explorer仪器， 我在13年前（2009年）在斯坦福大学刚开始我的实验室时购买了它，现在已经不再是了。 有用我们提供了来自当前供应商（Cytiva）的文档，该文档支持这种旧的 AKTA_Explorer系统于2018年失效。部件不可用，供应商支持不可用， Microsoft或Cytiva均不支持运行仪器软件所需的操作系统。我们 密集使用（每周约20-30小时）和特定于项目的配置排除了成本效益和 在斯坦福大学的核心设施中高效地使用色谱系统。最后，改进的自动化 新系统附带的软件将大大加快我们的工作流程， 可重复性，并为学员提供蛋白质纯化和分析核心技能的最新培训 在NIGMS资助的项目上工作斯坦福大学的生物化学系将支持此次收购 同时提供仪器服务资金和安装AKTA_Pure FPLC系统的空间。

Supplement Summary Administrative supplement application for equipment purchase This is an administrative supplement application for the purchase of a AKTA_Pure Fast Pressure Liquid Chromatography (FPLC) system from Cytiva. The AKTA_Pure FPLC is a medium flow, medium pressure chromatography system that allows the semi-automated, rapid, and high-resolution chromatographic separation of proteins by ion-exchange, hydrophobic interaction, gel-filtration, and affinity chromatography. Protein purification and analysis, enabled by the FPLC, is a central and indispensable requirement for all the projects being pursued in my laboratory as part of my NIGMS-funded R35/MIRA award. The new AKTA_Pure FPLC being requested in this supplement will directly replace a malfunctioning AKTA_Explorer instrument that I purchased 13 years ago (in 2009) when I first started my laboratory at Stanford and that is no longer serviceable. We provide documentation from the current vendor (Cytiva) that support for this old AKTA_Explorer system lapsed in 2018. Parts are not available, vendor support is not available and the operating system required to run instrument software is not supported by either Microsoft or Cytiva. Our intensive use (~20-30 hours per week) and project-specific configurations preclude the cost-effective and time-efficient use of chromatography systems in core facilities at Stanford. Finally, the improved automation and software that comes with the new system will dramatically accelerate our workflows, improve reproducibility and provide up-to-date training in the core skills of protein purification and analysis for trainees working on our NIGMS-funded projects. The Biochemistry Department at Stanford will support this purchase with both funds for instrument service and space to house the AKTA_Pure FPLC system.
