Figure 2.

Scaling of the intercept and initial gradient with a varying initial seed concentration at a fixed initial monomer concentration as predicted by Eqs. 3 and 5. (A) Example of raw data (using VA37) for the early-time evolution of the polymer mass at increasing seed concentration (bottom to top). (B) The slope of the initial linear growth phase shows a linear dependency with the seed concentration. (C) The intercepts obtained from linear regression of the initial linear phases also reveal a linear dependency on the seed concentration. The fixed monomer concentration was 100 μM and the data (both seed and monomer) for the variants AG35 (circle), IA8 (square), and VA37 (diamond).
