Interpretive Summary: This manuscript provides a detailed methodology for the chemical activation of antibodies to reporter molecules for their use in the detection of specific targets used in diagnostic assays.

Technical Abstract: The bioconjugation of an antibody to an enzymatic reporter such as horseradish peroxidase (HRP) affords an effective mechanism by which immunoassay detection of a target antigen can be achieved. The use of heterobifunctional cross—linkers to covalently link antibodies to HRP provides a simple and convenient means to maintain antibody affinity while imparting a functional reporter used for antigen detection. In this chapter we describe a process by which sulfo-SMCC is used to generate a stable maleimide--activated HRP that is reactive with sulfhydryl groups generated in antibodies by SATA mediated thiolation.
