Mass fractions of small intermediates as functions of time for varying initial capsomer concentrations. Each figure shows mass fraction versus time of monomer, dimer, trimer, tetramer, pentamer, and hexamer oligomers for the best-fit parameters at a distinct concentration: (a) 100 μg/ml. (b) 300 μg/ml. (c) 500 μg/ml. (d) 1000 μg/ml.
