Abstract
High-throughput screening method and apparatus are described. The method includes placing cells on a substrate defining a plurality of discrete microwells, at a well density of greater than about 100/cm2, with the number of cells in each well being less than about 1000, and where the cells in each well have been exposed to a selected agent. The change in conductance in each well is determined by applying a low-voltage, AC signal across a pair of electrodes paced in that well, and synchronously measuring the conductance across the electrodes, to monitor the level of growth or metabolic activity of cells contained in each well. Also disclosed is an apparatus for carrying out the screening method.
Claims5
A high throughput screening method comprising
- placing cells on a substrate defining a plurality of discrete microwells on a substrate surface, at a well density of greater than about 100/cm2, with the number of cells in each well being less than about 103,
- where the cells in each well have been exposed to a selected agent, and
- determining the conductance in each well, by applying a low-voltage, AC signal across a pair of electrodes placed in that well, and synchronously measuring the conductance across the electrodes, to monitor the level of growth or metabolic activity of cells contained in each well.
