  • Patent number: 4950613
    Abstract: A method of preparing a labelled specific binding partner, such as a biological probe in the form of an antibody or oligonucleotide probe, using a protected label (the corresponding unprotected label being susceptible to inactivation, such as by hydrolysis to yield a non-chemiluminescent form of the label). The specific binding partner is linked to the label, and an adduct of the label is prepared using a protective adduct former which produces a protected label which is less susceptible to inactivation. Particularly preferred labels are the acridiniums and acridans, most preferably the former having the general structure: ##STR1## wherein the phenyl rings are optionally additionally substituted, R.sub.1 is preferably an alkyl, and R.sub.5 is an optionally substituted hydrocarbon, most preferably a phenyl moiety which is either linked to the specific binding partner, or capable of being linked thereto.
