Abstract

Double immunoenzymatic labelling procedures for the localization of antigens on cells in tissue sections using horseradish peroxidase (HRP) and alkaline phosphatase have been described previously, but mainly for detecting antigens on different cells. With this type of staining when two antigens are present on the same cell, an optimal colour combination that shows a high contrast between the basic colour of each enzyme substrate product is difficult to achieve and the interpretation of their mixed colour intermediate is subjective. We present a method for the simultaneous demonstration of two antigens on the same cell. The method can be used to label either single cells in suspension, or cells in paraffin fixed, tissue using a combination of a particulate label, colloidal immunogold-silver, and an enzymatic label HRP-DAB. The method is easy to perform and utilises commercially available staining kits.
