  We characterize the self-assembly of colloidal particles with surface mobile
DNA linkers under kinetically limited valence conditions. For this, we put
forward a computer simulation model that captures quantitatively the interplay
between the main dynamic processes governing these systems and allows the
simulation of the long time scales reached in experiments. The model is
validated by direct comparison with available experimental results, showing an
overall good agreement that includes measurements of the average effective
valence and its probability distribution as a function of the density of DNA
linkers on the particles surface. Finally, simulation results are used to
evidence the opposite impact of particle density and characteristic DNA
hybridization time on the effective valence.
