The present application provides compounds and methods for identifying a modulator of a protein of interest using TR-FRET donor attached to the protein of interest and a tracer containing TR-FRET acceptor. Iterations of this compound may also includes attachment of an ATP-binding moiety, an amino acid, and/or a fluorophore.

Cell permeable metal ion indicator compounds and methods of their use and synthesis are described. The compound comprises a metal chelating moiety (M.sub.c), a reporter molecule and two or more lipophilic groups (G.sub.L) covalently bonded through a linker to the reporter molecule, wherein the lipophilic groups, when present in a live cell, are cleaved resulting in two or more negatively charged groups.

A composition includes a functionalized fluorescent dye. The functionalized fluorescent dye includes an isothiocyanate-containing dye that is functionalized with a functional group. The functional group includes a primary amine. The functionalized fluorescent dye can be mixed with a fluid to form a tracer fluid for tracing fluid flow in a subterranean formation.
