Abstract

The use of immunogold-silver staining (IGSS) combined with immunoperoxidase and/or immunoalkaline phosphatase methods for the simultaneous demonstration of pancreatic islet cell hormones on routinely fixed paraffin-embedded human tissue sections was examined. If IGSS was applied first, the black colour of silver-enhanced colloidal gold on doubly immunostained sections contrasted with the colours of most of the chromogens used generally in the 2 immunoenzymatic methods. If IGSS was followed by immunoalkaline phosphatase and immunoperoxidase techniques in optional sequence, 3 different hormone-containing cell types could be stained simultaneously without non-specific cross-reactions. IGSS and immunoalkaline phosphatase methods, together with 2 kinds of non-cross-reacting immunoperoxidase systems, permitted the detection of 4 distinct antigens on the same tissue section. Multiple immunohistochemical labelling of the endocrine pancreas provides an opportunity for the correct and rapid analysis of the topographic and morphometric relationships between different hormone-producing cell populations under both normal and pathological conditions. IGSS is of great potential for the simultaneous immunolabelling of antigens situated within separate cells.
