Detection of Covalent Binding

Abstract

Immunochemical detection of xenobiotics covalently bound to cellular proteins can provide information about toxic mechanism and is more specific than the alternative radiochemical studies. Both immunoblotting and immunohistochemical methods are used to pinpoint the target protein(s) and to identify the tissue targets. Also included in this unit are protocols for synthesizing artificial antigens, immunizing suitable host species, and using noncompetitive and competitive ELISA assays to characterize the antibodies produced.
