[Transformation of serum immunoglobulins and monoclonal antibodies into polyreactive immunoglobulins].
It was shown that polyreactive properties of natural serum immunoglobulins or some monoclonal antibodies (i.e. their ability of binding to various antigenically dissimilar antigens) can be induced by the treatment with chaotropic ions (3.5 M KSCN, 5-30 min at 20 (C). Such transformation of monoclonal antibodies or serum immunoglobulins into polyreactive immunoglobulins (PRIG) seems to result of the changes in immunoglobulin conformation but is not from their unblocking. Interaction of PRIG with some antigens immobilized on the plate is strongly dependent on temperature unlike that of monospecific antibodies.
