Figure 1From: The quantal theory of how the immune system discriminates between "self and non-self"The IL2 binding and biological response curves are coincident. Radiolabeled IL2 and purified homogeneous IL2 were used in parallel experiments with the same IL2R+ T cell population to determine the relationship between IL2 binding and IL2-promoted T cell proliferation as monitored by 3H-TdR incorporation.
