Figure 24. BINDING OF 125 I-CON A TO A- 9 AND LAN-2 CELLS 



Duplicate 80% confluent monolayers of cells were exposed 

 to increasing concentrations of -"-^I-Con A (S.A. = 2 x 

 10^ cpm/yg) for 15 minutes at 22°C. The binding of the 

 maximum 125i_con A dose was 99% inhibitable by 30 minutes 

 preincubation of the cells with Con A (100 ug/ml) .
