Pepsinogen
has previously been shown to bind non-specifically to immune complexes and aggregated immunoglobulins. We demonstrate here using a solid-phase immunoassay that immunoglobulins aggregated by heat or glutaraldehyde bind non-specifically to several different enzymes. Some of these, including pepsinogen (marketed as pepsin),
hyaluronidase
and trypsin, are used in the breakdown of tissues or biochemical preparations during the preparation of antigens. Contamination of impure antigens by enzyme is likely to lead to products which bind non-specifically to immune complexes. This can cause misidentification of complexes as antibodies. We recommend that all tests for specific antibody involving the use of antigens prepared by these or other enzymes should include a control with aggregated immunoglobulin substituted for the test serum.
