Statistics of Th, the random time to reach the nucleus in Bcell1.

The diffusing molecule is assumed to initially be randomly distributed on the cell membrane, ∂Ch. Here STD denotes standard deviation and CV denotes the coefficient of variation (the standard deviation divided by the mean). Values in parenthesis denote the ratio of the physiological value to the corresponding no ER or no organelle values. See Table A of S1 Text for statistics in Bcells 2 and 3.
