  • Publication number: 20180224452
    Abstract: The present invention, in some aspects, relates to systems and methods for determining oxidized proteins, including glutathionylated proteins such as S-glutathionylated proteins. The systems and methods of the invention can be used in vitro (e.g., in cell or tissue culture) or in vivo, for example, to diagnose a person having an oxidative stress condition. For instance, in some cases, the invention can be used to spatially determine the location and/or concentration of oxidized proteins within cells and/or tissues (e.g., through visual detection). In one set of embodiments, a glutathionylated or otherwise oxidized moiety on a protein may be reacted with a detection entity, which may be, for example, fluorescent, radioactive, electron-dense, able to bind to a signaling entity or a binding partner in order to produce a signal, etc.
