  • Dry reagent test strip comprising benzidine dye precursor and antipyrine compound
    Patent number: 5824491
    Abstract: A dry reagent test strip for determining the concentration of an analyte in a liquid sample is described. The test strip has a matrix containing reagent detection chemistry, which includes an oxidase enzyme that can utilize the analyte as a substrate forming hydrogen peroxide, a benzidine dye precursor, a peroxidase enzyme, and an antipyrine compound. The addition of an antipyrine compound to the reagent detection chemistry provides a standard concentration graph which is substantially linear in a desired range of analyte concentration. The precision and accuracy of reading the test strip are enhanced.
