An index of the binding affinity of a hormone for its receptor can be obtained by examining the
Scatchard plots of hormone-receptor binding data give information regarding the number of receptors and the affinity of the hormone for its receptor. The x-intercept provides data regarding total receptor number, and the slope is equal to the negative of the association constant (-Ka).
