Figure 23. BINDING OF 125 I-CON A TO CHO H-7 AND 

 H-7 WCR CELLS 



Duplicate 80% confluent monolayers of cells were 

 exposed to increasing concentrations of 125j_c on a 

 (S.A. = 2 x 10 4 cpm/ijg) for 15 minutes at 22°C. The 

 binding of the maximum 125j_ Con A dose was 89?, inhi- 

 bitable by 30 minutes preincubation of the cells with 

 Con A (100 yg/ml ) .
