  • OPTICALLY-DETECTABLE ENZYME SUBSTRATES AND THEIR METHOD OF USE
    Publication number: 20120040380
    Abstract: The present invention relates to compounds that are substrates for an enzyme, and upon reaction with the enzyme provide a detectable response, such as an optically detectable response. In particular, the compounds have utility in detecting the presence of a ?-lactamase in a sample. In addition to the compounds, methods are disclosed for analyzing a sample for the presence of a ?-lactmase, for example, as an indicator of expression of a nucleic acid sequence including a sequence coding for a ?-lactmase. Kits are disclosed that include the disclosed compounds and additional components, for example, cells, antibodies, a ?-lactmase or instructions for using the components in an assay.
