Abstract
Novel conjugated enzyme compositions are provided for use in homogeneous immunoassays. A wide variety of haptenic compounds, such as drugs of abuse, therapeutic drugs, naturally occurring hormones, and the like, are conjugated to the enzyme lysozyme for use as reagents in homogeneous enzyme immunoassays. From 1 to 5 haptens are conjugated to the enzyme, and the enzyme is substantially inhibited when bound to antibodies bound to the conjugated hapten.
