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.
