we have used indirect immunogold electron microscopy to compare the respective density of cell membrane determinants revealed by okt6 and okt4 monoclonal antibodies on normal human langerhans cells ( lc ) : 12.9 +/- 3.5 gold granules were noted per cell section on okt4-positive lc whereas 236.8 +/- 23.5 granules were counted per cell section on okt6-reactive cells .
