Abstract
A new method for demonstrating antigens in paraffin sections of formol sublimate-fixed tissue is described that utilizes an "indirect" immunohistological technique employing immunoglobulin adsorbed to colloidal gold as the secondary antiserum. The gold particles introduced to antigenic sites are revealed by a silver precipitation reaction. This technique, the immunogold-silver staining method, is of much enhanced sensitivity (up to 200-fold) as compared with standard immunoperoxidase and immunogold staining methods. The results have been confirmed in a study of immunoglobulins in reactive human tonsil. The use of this new method for double immunolabeling is also described.Entities:
