    Abstract: ABSTRACT Described herein are compounds, compositions, methods, and kits for detecting reactive oxygen species (ROS) by conventional fluorescence microscopy, fluorescence spectroscopy, flow cytometry, and/or high content imaging. The compounds disclosed herein are novel reduced dyes, including Cy-based hydrocyanine dyes and Cy-based deuterocyanine dyes, which dyes are probes for detecting ROS and measuring oxidative stress in cells either in vitro and/or in vivo. Also described herein are processes for preparing novel reduced dyes, i.e., ROS probes, for use in the disclosed compositions, methods and kits.

    Abstract: The present invention presents designs for high extinction quenched "dyedrons" that can be activated by conversion of a single acceptor/quencher in the molecular assembly to a fluorescent state. The quencher is activated by noncovalent binding to a unique complementary expressible fluorogen activating peptide (FAP). In this way, the quencher serves as the homogeneous switch, receiving energy efficiently from each of the donor molecules of the dendronic antenna, and releasing it as fluorescence only when activated by binding. The sum of the extinction of the multiple dyes on the antenna will provide dramatic enhancements in the effective brightness of the probe in standard imaging systems. This approach provides a set of probes with exceptional brightness, specifically targeted to an expressed tag that activates the fluorescence of the dyedron.

    Abstract: The invention provides compounds and compositions of Formulas I-VII, and methods of using the compounds. The compounds can be used to prepare dye conjugates that are uniformly and substantially more fluorescent on proteins, nucleic acids or other biopolymers, than conjugates labeled with structurally similar known carbocyanine dyes. In addition to having more intense fluorescence emission than structurally similar dyes at virtually identical wavelengths, and decreased artifacts in their absorption spectra upon conjugation to biopolymers, the compounds can have greater photostability and/or higher absorbance (extinction coefficients) at the wavelength(s) of peak absorbance than such structurally similar dyes.
