Abstract: An apparatus and method for real-time measurement of an effect of different concentrations of a test compound or series of test compounds on living cells, in which a flow of cell suspension is combined with a flow of the test compound and a cellular response of the living cells is repeatedly measured by a detector along a length of a detection zone where the cell suspension-test compound mixture is situated. The apparatus may be used in automated screening of libraries of compounds, and is capable of real-time variation of concentrations of test compounds and generation of three-dimensional dose/response/time profiles within a short timespan.

Abstract: The present disclosure provides compositions and methods for high throughput Gain of Function (GOF) sorting to discover and develop novel and highly selective candidate drug molecules. High throughput GOF sorting includes: mutating a single residue in a receptor and/or ligand; measuring the affinity and functional activity of the resulting ligand target-ligand interaction; and carrying out multiple rounds of mutation and measurement to determine which residues provide key interaction points underlying the functional activity of a ligand target-ligand interaction. Further, the present disclosure provides methods and compositions for high throughput and high precision GOF sorting, such that large numbers of mutations can be generated and screened rapidly, and GOF compounds can be identified and isolated.

Abstract: The present disclosure provides systems for multiplexed multitarget screening of cell populations having one or more wild type or mutated ligand targets and measuring cell responses to ligands using high throughput screening techniques, including flow cytometry (FCM). The method includes the steps of: 1) developing cell populations to be screened; 2) staining cell populations using one or more fluorochromes to yield a distinct excitation/emission signature for each cell population; 3) combining labelled cell populations into a single mixed suspension; 4) analyzing populations to resolve them on the basis of their unique signature; and 5) resolving individual populations and deconvoluting data to extract meaningful information about populations.

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 homogenous 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.

Abstract: Sensitive methods for identifying compounds having biological activity comprising combining living cells with two fluorescent membrane permeable ionic dyes having the same charge sign, the first of which has an emission spectrum which overlaps the excitation spectrum of the second fluorescent membrane penetrative dye. The fluorescence is then induced by illuminating the dyes at a wavelength corresponding to the excitation spectrum of the first fluorescent dye and emission is then registered at a wavelength corresponding to the emission spectrum of the second fluorescent dye (FRET). The change in the FRET is indicative of a modulation of cell membrane potential by the biologically active compounds.
