REDUCIBLE INDICATOR COMPOSITIONS CONTAINING PYROGALLOL DERIVATIVES AND USES THEREOF

摘要

The invention relates to a composition useful in determining an analyte in a sample. The composition contains an indicator system which forms a detectable signal in the presence of said analyte, and which is not a coupling system, as well as a pyrogallol derivative. The pyrogallol derivative causes uniform formation of detectable signal. Also described are kits useful in determining an analyte, apparatus which incorporate the composition, and a method for determining an analyte using the composition.
