Abstract: Methods, compositions and articles of manufacture for encoding a cell with semiconductor nanocrystals and/or other fluorophors are provided. The encoded cells can be subjected to functional assays in mixed populations, and an assay result can be determined and associated with individual cells by virtue of their code. The methods are particularly useful in multiplex settings where a plurality of encoded cells are to be assayed.

Abstract: Semiconductor nanoparticle complexes comprising semiconductor nanoparticles in association with cationic polymers are described. Also described are methods for enhancing the transport of semiconductor nanoparticles across biological membranes to provide encoded cells. The methods are particularly useful in multiplex settings where a plurality of encoded cells are to be assayed. Kits comprising reagents for performing such methods are also provided.

Abstract: This invention provides principles, methods and compositions for ascertaining the mechanism of action of pharmacologically important compounds in the context of network biology, across the entire scope of the complex pathways of living cells. Importantly, the principles, methods and compositions provided allow a rapid assessment of the on-pathway and off-pathway effects of lead compounds and drug candidates in living cells, and comparisons of lead compounds with well-characterized drugs and toxicants to identify patterns associated with efficacy and toxicity. The invention will be useful in improving the drug discovery process, in particular by identifying drug leads with desired safety and efficacy and in effecting early attrition of compounds with potential adverse effects in man.

The encoded cells can be subjected to functional assays in mixed populations, and an assay result can be determined and associated with individual cells by virtue of their code. The methods are particularly useful in multiplex settings where a plurality of encoded cells are to be assayed. The methods are used in screening methods for G protein coupled receptors (GPCRs), for identifying the ligands and functions of orphan GPCRs, and for screening for modulators of GPCRs. Kits comprising reagents for performing such methods are also provided.
