Preference for IgG mAb binding insulin in solution or on surfaces is related to immunoglobulin variable region structures.

Abstract excerpt

Studies on insulin autoantibodies often show a lack of correlation between enzyme-linked immunosorbent assays (ELISAs) and fluid phase radioimmunoassays (RIAs). Similarly, a set of IgG anti-insulin monoclonal antibodies (mAb) from BALB/c mice are found to differ in their binding in ELISAs and RIAs. To understand the structural basis for differential insulin binding, soluble and complexed biotinylated insulin is...
