  • Cell-based assay for the detection of toxic analytes
    Patent number: 7214505
    Abstract: Cell-based reagents and methods of using the reagents for detecting analytes are provided. The adsorbing of cells with signal-generating metabolic activity to solid supports has been found to improve the sensitivity of known cell based assays. Signal-generating cells adsorbed to a solid support are introduced to a test agent, and the measured decrease in metabolic signal provides a measure of the toxicity of the test agent.
