Figure 2From: A danger of low copy numbers for inferring incorrect cooperativity degreeFraction of bound proteins (pure initial state). Does response curves for the system prepared in a pure state: 〈 L 0 2 〉 = L 0 2 and 〈 P 0 2 〉 = P 0 2 The curves were obtained in the same way as for Fig. 1. The thickest full line is the reference Hill curve obtained with K = 1. Other curves describe the effects of fluctuations and were obtained using the PARNES method: the full (P0 = 2), the dashed (P0 = 3), the dotted (P0 = 4), and the dot-dash (P0 = 8). The thinner curves approach the reference mean field curve for large values of P0. The curves are distinct and their shape depends on the value of P0.Back to article page
