  • Detection of hydrolyzing enzymes
    Patent number: 4782018
    Abstract: A composition of a polysaccharide with a detectable material appended thereto and a 1,3-dione having a methylene group between the two carbonyls of the 1,3-dione, which methylene group has at least one ionizable hydrogen, provides accurate results in assays of hydrolyzing enzymes such as amylase. The composition can be incorporated in the reagent zone of a dry test element having a reagent zone and a registration zone.

  • Overcoat compositions and ion-selective electrodes for ionic analyte determinations
    Patent number: 4505801
    Abstract: An overcoat composition for use in ion-selective electrodes comprises: (a) a discontinuous liquid phase comprising an oleophilic solvent dispersed within a continuous phase comprising a hydrophilic binder; (b) a complexing agent useful for extracting oleophilic anions; (c) a buffer which provides a pH in the range of from about 7.5 to about 9.5 under conditions of use; and (d) a nucleating agent. This overcoat composition is particularly useful in ion-selective electrodes for determination of CO.sub.2.
