the binding of rhil-2 was blocked by crude bovine il-2 , and scatchard plot analysis of the binding data showed that both phenotype cells expressed two different affinity il-2r that had equilibrium dissociation constants of 12-20 pm ( 3000-6000 sites/cell ) and 146-490 pm ( 16,000-25,000 sites/well ) .
