Binding rate constant

Webon is the second-order rate constant of the binding reac-tion. Its units are M 1s . This rate constant has an upper limit due to the fact that the two molecules must collide before binding. For two molecules moving in solution (free diffusion), the maximum value of K on is about 1 109 M 1s 1 [4]. K off is the first-order rate constant for the ... WebIt is now realized that binding mechanisms, like binding rate constants, can and should be quantitatively determined.
