  • Binder composition and analytical element having stabilized peroxidase in layer containing the composition
    Patent number: 5155024
    Abstract: An analytical element has a peroxidase-labeled ligand analog distributed within a water-soluble binder composition comprising at least about 50 percent, by weight, of poly(vinyl alcohol). As a result, the peroxidase retains more of its stability prior to use. Such elements can be used to determine any of a number of immunologically reactive analytes, such as digoxin.
