Apoenzyme Reactivation Immunoassay ARIS

Both competitive and noncompetitive methods have been incorporated into homogeneous enzyme-labeled immunoassay kits that ultimately relate enzyme activity to analyte concentration.22 The competitive-binding assays are called enzyme-multiplied immunoassay technique (EMIT), substrate-labeled fluorescein immunoassay (SLFIA), apoenzyme reactivation immunoassay (ARIS), and cloned enzyme donor immunoassay (CEDIA), while a noncompetitive method is called enzyme inhibitory homogeneous immunoassay (EIHIA).
