ABSTRACT:
The present invention is directed to a reliable redox indicator composition for use in chemical assay systems and is particularly well suited for assay systems using a dry phase format. More specifically, the improved indicator composition of this invention is directed to the use of a divalent metal complex to prevent unwanted metal hydroperoxide mediated and similar-type oxidation of redox indicators. A fundamental element of the present invention involves the use of divalent metal complexes of the general formula: ##STR1## wherein M is either Zn(II), Co(II), Mn(II), or Rb(II).
