Abstract
Chemiluminescent-labeled conjugates of the formula: ##STR1## wherein one of R.sup.1 and R.sup.2 is hydrogen and the other is --NR.sup.3 R.sup.4 ; R.sup.3 is hydrogen or straight chain alkyl containing 1-4 carbon atoms and R.sup.4 is EQU L(CO)--HN--(CH.sub.2).sub.n wherein n=2-8 and L(CO)-- is an antigenic protein or polypeptide bound through an amide bond. The labeled conjugates are useful as reagents in specific binding assays for determining antigenic proteins or polypeptides, or their binding partners, in liquid media.
