Figure A2.

Comparison of the best fit functions. The readout intensity of the reporter constructs with 8, 12 (transfected), and 12 (integrated) TBEs (A–C) are plotted with standard deviations. The linear activation function (light gray), the Michaelis–Menten activation function (dark gray), and the Hill-type activation function (black) realizing the best fit (i.e., yielding the minimal log-likelihood function values) are shown for each reporter construct. Note, that the fits of the linear and the Michaelis–Menten activation lie on top of each other. The experimental data was kindly provided by Biechele and Moon (2008).
