High molecular mass forms have been reported for many serum enzymes measured in clinical
laboratories. They are described as either type-1 (a normal enzyme complexed with
an immunoglobulin by an antigen-antibody reaction) or type-2 macroenzymes (all other).
They are detected in patients examined for persistently increased levels using electrophoretic,
chromatographic or immunoinhibition methods, but are indistinguishable from normal
enzymes in routine quantitative assays [
