Influence of DNA length and concentration on the reaction time. (a) Biotin-streptavidin association experiments are repeated for different DNA lengths. Reaction times τ are presented as a function of DNA concentration. (b) Plotting the dependencies of the reaction times on DNA base pair concentration results in curve clustering together in three regions: I) no speed-up due to an insufficient number of DNA molecules per binding partner; II) maximum speed-up with the optimal amount of DNA per binding partner; III) reduced speed-up caused by the amount of DNA being so high that the probability of binding partners to meet on the same DNA molecule diminishes.
