项目摘要
High throughput live-cell microarray screening technology for dynamic, multiparameter sensing cf single-cell
metabolic phenotypes is proposed. The proposal addresses Common Fund priorities by extending the range
of signatures available to the LINCS centers. A sandwich microarray, called the "Cellarium" will be
developed and used to analyze individual live cells. The bottom layer ofthe sandwich supports cells in
shallow microwells etched in glass. The top layer ofthe sandwich seals the cells in the 150-picoliter
microwells, and incorporates extracellular fluorescent sensors for multiparameter detection ofthe metabolic
analytes, oxygen, pH and glucose. Chemical isolation is achieved when the two layers are compressed
together with a flat metal spring allowing dynamic measurement of transmembrane fluxes without
Intracellular probes. Single-cell analysis which directly reveals heterogeneity in metabolic response to
perturbations within an isogenic cell population is critical to biological inference. This microarray is an
extensible tool for deriving a standardized multiparameter set of data that can be integrated in a coordinated
way into LINCS. The specific aims ofthe project are: 1) develop a disposable microarray ("Cellarium") for
dynamic, high throughput, multiparameter metabolic measurements of perturbation-induced signatures of
live single cells; 2) modify a commercial microarray scanner to read out the Cellarium; 3) verify the
effectiveness of this technology across a range of cell types by simultaneously monitoring 02, pH, glucose
and ATP responses; 4) validate the platform by analyzing the distribution of metabolic signatures of single
cells in response to perturbations; 5) develop written and graphical standard operating procedures that
enable reproducible data generation; 6) develop active participation with LINCS partners in the instrument
development process to ensure efficient device and methods translation.

活单细胞; 2)修改商业微阵列扫描仪以读出Cellarium; 3)验证
该技术通过同时监测O2、pH、葡萄糖
和ATP响应; 4)通过分析单个细胞的代谢特征的分布来验证平台。
5)制定书面和图形化的标准操作程序,
能够生成可再现的数据; 6)与LINCS合作伙伴一起积极参与仪器
开发过程,以确保有效的设备和方法翻译。
