Antinucleolar antibodies (Si87) were obtained from a scleroderma patient. The specificity of immunostaining was verified and morphological changes in nucleoli were monitored using a fluorescence microscope. Fluorescence of propidium iodide-stained DNA and nucleolar immunofluorescence were measured by flow cytometry. Following phytohaemagglutinin stimulation the number of nucleoli of normal human peripheral blood lymphocytes increased about 3-fold, accompanied by enlargement of nucleolar size. Simultaneously a mean increase in total immunofluorescence per cell by a factor of three was detected.
