Web21. máj 2004 · Redox-sensitive green fluorescent proteins (GFP) allow real time visualization of the oxidation state of the indicator. Ratios of fluorescence from excitation at 400 and 490 nm indicate the extent of oxidation and thus the redox potential while canceling out the amount of indicator and the absolute optical sensitivity. The reduction-oxidation sensitive green fluorescent protein (roGFP) is a green fluorescent protein engineered to be sensitive to changes in the local redox environment. roGFPs are used as redox-sensitive biosensors. In 2004, researchers in S. James Remington's lab at the University of Oregon constructed the first roGFPs by introducing two cysteines into the beta barrel st…
