1. A diagnostic kit for simultaneously detecting two parameters comprising:
- (i) a cell comprising a chimeric nucleic acid sequence comprising in the 5′
to 3′
direction of translation as operably linked components a first nucleic acid construct comprising;
(a) a first promoter operable in the cell; and
(b) a nucleic acid sequence encoding a first reporter polypeptide comprising a first hydrolase capable of hydrolyzing a first substrate comprising a first electoactive analyte and a first carrier and releasing the first electroactive analyte from the carrier; and
a second nucleic acid construct comprising;
(c) a second promoter operable in the cell; and
(d) a nucleic acid sequence encoding a second reporter polypeptide comprising a second hydrolase capable of hydrolyzing the second substrate comprising a second electroactive analytes and a second carrier and releasing the second electroactive analyte from the carrier;
(ii) a first and second substrate; and
(iii) instructions for use or storage of the kit, wherein the first and second hydrolase are independently selected from the group of hydrolases consisting of β
-D-glucosidase, β
-D galactosidase, and β
-D-glucuronidase, and wherein the first and second substrate are independently selected from the group of substrates consisting of chlorophenol red-β
-D-galactopyranoside (CPRG), para-nitrophenol-β
-D-glucuronide (PNPG) and para-diphenol-β
-D-glucopyranoside (PDPG).
