Richard: Colloidal gold is used as the label in many antibody-mediated diagnostic tests. It has an excellent shelf life and, when used in a "sandwich" antibody assay, leaves nice reddish lines to read at test and control positions on the wick. Go to google.com and type in "colloidal gold antibody assay" as the search term. You'll find gold is a conventional reagent in numerous throw-away, off-the-shelf antibody diagnostic tests. Also, don't forget its use as a sputter coating for preparing samples for scanning electron microscopy.
