Detection of cell surface antigens in cryostat sections with immunogold-silver staining.
Immunogold-silver staining was used for the detection of lymphocyte cell surface antigens in cryostat sections of lymphoid tissues. The sections were incubated with monoclonal mouse antibodies and then with colloidal gold-labeled goat anti-mouse antibodies. They were then immersed in a physical developer, counterstained, and mounted. In light microscopy, the tissue architecture was well preserved, and a dark labeling was seen on the positive cells. Optimal labeling conditions were determined. The distribution of the lymphocyte subsets, as defined by a panel of monoclonal antibodies in tonsil and reactive lymph nodes, was similar to that found with a biotin-avidin-horseradish peroxidase method. The monoclonality of the neoplastic cells in lymph nodes of B-cell non-Hodgkin's lymphomas clearly could be demonstrated. The sensitivity of the technic was comparable with that of the biotin-avidin-horseradish peroxidase labeling method. In addition, immunogold-silver labeling was combined with acid phosphatase cytochemistry.
