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 ... WebJan 19, 2024 · The shape of the curves is highly dependent on the dissociation rate constant. In the figure are five dissociation rates (10-1 – 10-5 s-1) with the same association rate (10 5 M-1 s-1) and an analyte concentration of 1 times K D. The curve with the fastest dissociation rate will reach steady state much quicker compared to the other.
