Use of the CellCard System for analyzing multiple cell types in parallel.

The CellCard system enables the analysis of multiple cell types within a single microtiter well. In doing so, the CellCard system not only determines the effect of an experimental condition on a cell type of interest, but also the relative selectivity of that response across nine other cell types. In addition, this approach of cellular multiplexing is a means of miniaturization without the necessity of microfluidic devices.

Bringing primary cells to mainstream drug development and drug testing.

Although cell-based screening is already an essential tool in drug discovery, the cell models currently available are fast becoming inadequate. The use of transformed cells as models in almost every step of the discovery pipeline needs to be substituted with more relevant, disease-oriented models, and the use of patient-derived primary cells should logically become the next best strategy. In the past the use of such cells has been restricted by their scarcity and difficulty in manipulation and general handling; however, recent advances in isolation and growth, as well as assay miniaturization, transfection efficiency and assay sensitivity, have enabled their use in the mainstream of drug discovery.

The CellCard System: a novel approach to assessing compound selectivity for lead prioritization of G protein-coupled receptors.

Advances in high throughput screening technologies have led to the identification of many small molecules, "hits", with activities toward the target of interest. And, as the screening technologies become faster and more robust, the rate at which the molecules are identified continues to increase. This evolution of high throughput screening technologies has generated a significant strain on the laboratories involved with the downstream profiling of these hits using cell-based assays.

A novel encoded particle technology that enables simultaneous interrogation of multiple cell types.

The authors have developed a cellular analysis platform, based on encoded microcarriers, that enables the multiplexed analysis of a diverse range of cellular assays. At the core of this technology are classes of microcarriers that have unique, identifiable codes that are deciphered using CCD-based imaging and subsequent image analysis. The platform is compatible with a wide variety of cellular imaging-based assays, including calcium flux, reporter gene activation, cytotoxicity, and proliferation.

High-throughput cell analysis using multiplexed array technologies.

The desire for more biologically relevant data from primary screening has resulted in a dramatic increase of cell-based assays in HTS labs. Consequently, new cell-array technologies are being developed to increase the quality and quantity of data emerging from such screens. These technologies take the form of both positional and non-positional formats, each with their own advantages.
