The NSERC-funded research programs of principal investigators from the Health Sciences, Neuroscience, Biochemistry and Biology departments of Carleton University (CU) have been hindered by the absence of a live-cell imaging platform on campus. The original and highly innovative molecular biology, immunology and microbiology research programs of at least 6 internationally-recognized scientists rely heavily on cell imaging to study diverse biological questions and are compromised without availability of an automated, high-content live-cell microscope system. A critical issue is that our current microscopes limit users to end-point analyses of cell phenotypes. These end-point analyses require setting up parallel experiments for acquisition of multiple time points, provide limited coverage for each experiment, and are resource, time, and labor intensive. Most critically, end-point analyses do not fully reflect the dynamic nature of biological processes and are prone to human errors and therefore reduced experimental reproducibility. Execution of experiments with an automated platform will dramatically increase the number of experimental conditions (and cell lines) that can be analyzed in a single run and increase reproducibility. The ability to collect and analyze cell growth in real-time and simultaneously identify the outcomes of the treatments on the various cells (e.g. ROS, cytotoxicity, apoptosis, senescence) using commercially-available fluorescent reagents will maximize data collection, reduce cost, and greatly accelerate the research of all co-applicants. In addition, the real-time continuous imaging of cell viability, proliferation, growth, caspase activation and other phenotypes will also ensure that we never miss a phenotype, which is a constant concern when performing end-point assays. In this application we request funds for the acquisition of an IncuCyte S3 live-cell imaging platform for several research groups at Carleton University. The requested system is an affordable and easy-to-use automated microscope platform with the capacity to significantly advance fundamental molecular and cellular biology research at Carleton University. The S3 platform allows for straightforward identification of phenotypic changes by recording and tracking cell growth, cellular morphology, migration and invasion, or activation of specific pathways as a function of time in response to specific stimuli or inhibitors. The IncuCyte S3 platform will thus fill an important technological gap at Carleton University by providing real-time kinetic analysis of cell behavior over long time course experiments. This infrastructure will also allow us to foster new research partnerships within our institution and with external collaborators locally, nationally, and internationally. Consequently, this will greatly improve the funding competitiveness of our research programs at the national and international level, enhance our research capabilities and training of HQPs.

卡尔顿大学（CU）健康科学系、神经科学系、生物化学系和生物系的主要研究人员资助的nserc研究项目，由于校园内缺乏活细胞成像平台而受到阻碍。原创和高度创新的分子生物学、免疫学和微生物学研究项目，至少有6位国际公认的科学家在很大程度上依赖于细胞成像来研究各种生物学问题，如果没有自动化、高含量的活细胞显微镜系统，就会受到损害。一个关键的问题是，我们目前的显微镜限制了用户对细胞表型的终点分析。这些终点分析需要建立平行实验以获取多个时间点，为每个实验提供有限的覆盖范围，并且是资源、时间和劳动密集型的。最关键的是，终点分析不能完全反映生物过程的动态性质，容易出现人为错误，因此降低了实验的可重复性。使用自动化平台执行实验将大大增加可在单次运行中分析的实验条件（和细胞系）的数量，并增加可重复性。使用市售荧光试剂实时收集和分析细胞生长并同时识别各种细胞（如ROS，细胞毒性，细胞凋亡，衰老）的处理结果的能力将最大限度地收集数据，降低成本，并大大加快所有共同申请者的研究。此外，细胞活力、增殖、生长、caspase激活和其他表型的实时连续成像也将确保我们不会错过表型，这是在进行终点分析时经常关注的问题。在此申请中，我们请求为卡尔顿大学的几个研究小组购买IncuCyte S3活细胞成像平台提供资金。所要求的系统是一个价格合理且易于使用的自动化显微镜平台，具有显著推进卡尔顿大学基础分子和细胞生物学研究的能力。S3平台允许通过记录和跟踪细胞生长、细胞形态、迁移和侵袭，或特定途径的激活作为响应特定刺激或抑制剂的时间函数，直接识别表型变化。因此，IncuCyte S3平台将通过提供长时间过程实验中细胞行为的实时动力学分析，填补卡尔顿大学的一个重要技术空白。这种基础设施还将使我们能够在我们的机构内部以及与本地、国内和国际的外部合作者建立新的研究伙伴关系。因此，这将大大提高我们研究项目在国内和国际层面的资金竞争力，增强我们的研究能力和HQPs的培训。
