An immunogold cell labelling method for rat T lymphocytes

A method using monoclonal antibodies in conjunction with an immunogold procedure was adapted for labelling T lymphocytes in blood samples obtained from male Wistar rats. The monoclonal antibodies W3/25, MRC/OX8 and W3/13 were used. Changes in the percentages of positively labelled cells were observed in rats dosed with the immunosuppressant cyclosporin.
