    摘要： The present invention is directed to 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.

    摘要： Methods for increasing the stability of, or protecting, labile components, such as ethanolamine, growth factors, vitamins, etc., in compositions such as a cell culture medium, are described. Stability of the labile compound is increased either, by derivatization or by sequestering the labile compound. Sequestering can be done either by encapsulation within a microcapsule or by the use of sequestering agents. Encapsulation can provide controlled release of the susceptible compound being protected. These methods may improve or extend the storage conditions, the shipping and handling of media compositions comprising the labile compounds at room temperature rather than at lower temperatures, thereby decreasing shipping costs.
