Comparison of Λ. a) The coefficient of variation of BR₁ (calculated from Case I Figure 3)and BR₁R₂ complexes (calculated from Case II Figure 3) is compared. The variability of the system seems to be invariant in the presence of Type II. b) Concentration dependency of Λ as a function of R₂. c) Same as plot "a", however, direct interaction of BMP and Type II is allowed as in Case III, Figure 3. It's clear that the stochasticity of the system does not change over the range of values tested. d) Summary of BR₁R₂ formation and its impact on signaling noise.
