Abstract
Novel conjugated enzyme compositions are provided for use in homogeneous enzyme immunoassays. A wide variety of compounds, particularly drugs, including drugs of abuse, drugs used in repetitive therapeutic applications, hormones, and the like, are conjugated to malate dehydrogenase. The resulting products have a high turnover rate, so as to provide a high multiplication factor when employed in a homogeneous immunoassay, have long storage lives, and allow for the accurate and sensitive detection of compounds of interest.
