    摘要: The invention provides compounds, compositions, methods, substrates, and kits useful for analyzing the metabolic activity in cells, tissue, and animals and for screening test compounds for their effect on cytochrome P450 activity. In particular, a one-step and two-step methods using luminogenic molecules, e.g. luciferins or coelenterazines, that are cytochrome P450 substrates and that are also bioluminescent enzyme, e.g., luciferase, pro-substrates are provided. The present method further provides a method for stabilizing and prolonging the luminescent signal in a luciferase-based assay using luciferase stabilizing agents such as reversible luciferase inhibitors.

    摘要: The present invention provides haloalkane substrates, and linkers for connecting such substrates to functional elements (e.g., tags, labels, surfaces, etc.). Substrates and linkers described herein find use, for example, in labeling, detection, and immobilization of proteins, cells, and molecules. In particular, the linkers provided herein find use within substrates for dehalogenase variants that form covalent bonds with their haloalkane substrates.
