All parameters used are from the .BCT files for BCT1.1 provided by Matthew Levin from the Computational Biology Group in the Department of Zoology at the University of Cambridge.Bias does not reach 0.7, there is a lag in the response of bias to the 5 sec 1 uM Aspartate pulse as shown by Bray et al. Mol.Biol.Cell (1993) 4(5): 469-482. The June 2003 version of the BCT program is BCT4.3 and is available at the computational biology site of the Zoology department at Cambridge University.

Kd is calculated only for second order reactions, like nA+nB <->nC or nA<->nC+nD, where n is number and A,B,C,D are molecules, where as for first order reactions Keq is calculated. Kd for higher order reaction are not consider.
