Abstract
Composition and method are provided for enzyme immunoassays for high molecular weight proteins, such as ferritin. An enzyme is conjugated to the high molecular weight protein through a specific linking group. Usually, on the average, about 2 to 10 enzyme molecules are bonded to each protein molecule. In an assay, the conjugate competes with an unknown sample for receptor and the resulting enzymatic activity is compared to a standard for a determination of the presence and amount of protein in the unknown.
