Immunogold cell staining using monoclonal antibodies: application to lymphoid cells on coated slides.
The immunogold staining technique was presented for light microscopic detection of cell surface antigens with monoclonal antibodies. The lymphoid cells were adhered to glass slides precoated with the adhesive poly-(dimethyl-diallyl-)ammonium chloride. The staining with the monoclonal mouse antibodies followed by the gold labelled sheep anti-mouse antibody was carried out on the cells adhered to the slides. In spite of the adherence, the patching of the gold marker as the prerequisite for the light microscopic detection occurred and the positively stained cells were visualized. On basis of this method the content of T lymphocytes (BL-T2+), B lymphocytes (BL-Ig-L/1+) and monocytes (BL-M/G+) in the mononuclear cell fraction of peripheral blood was determined in a population of healthy donors and of patients. The content of T lymphocytes of 29 healthy donors was determined using the immunogold staining technique (66.7 +/- 10.4%) and the immunofluorescence technique (67.6 +/- 9.5%). The correlation between the results obtained with both methods was highly significant (p less than 0.001).
