Interpretive Summary: This manuscript provides detailed analysis of the biochemical structure and function of antibodies and how to use antibodies and their fragments in diagnostic assays.

Technical Abstract: Immunoglobulins (Ig) or antibodies are a powerful molecular recognition tools that can be used to identify minute quantities of a given target analyte. Their antigen binding properties define both the sensitivity and selectivity of an immunoassay. Understanding the biochemical properties of this class of protein will provide users with the knowledge necessary to select the appropriate antibody composition to maximize immunoassay results. Here we define the general biochemical properties of antibodies, their similarities and differences, explain how these properties influence their functional relationship to an antigen target and describe a method for the enzymatic fragmentation of antibodies into smaller functional parts.
