Apparatus and method for compound profiling of living cells
First Claim
1. An apparatus for determining the concentration-dependent response of living cells to an agonist, comprising:
- a cell suspension input that provides a constant flow of living cells;
an agonist input that provides varying concentrations of an agonist;
a mixing zone, fluidly coupled to said agonist input and said cell suspension input, for mixing said varying concentrations of said agonist with said living cells; and
a detector, fluidly coupled to the mixing zone, for measuring a response of the living cells to the varying concentrations of said agonist as said cells flow past said detector.

Abstract
An apparatus and method for real-time measurement of a cellular response of a test compound or series of test compounds (303) on a flowing suspension of cells (349), in which a homogeneous suspension of each member of a series of cell types (349) is combined with a concentration of a test compound (303), directed through a detection zone (355), and a cellular response of the living cells is measured in real time as the cells in the test mixture are flowing through the detection zone (355). The apparatus may be used in automated screening of libraries of compounds, and is capable of real-time variation of concentrations of test and standard compounds and generation of dose/response profiles within a short timespan.
