The regulation of I Open image in new window B, NF- Open image in new window B is of foremost interest in biology as the transcription factor NF- Open image in new window B has multiple target genes. We have modeled a previously published model by Hoffmann et al. (2002) of I Open image in new window B, NF- Open image in new window B mathematically as discrete reaction systems. We have used stochastic algorithm to compare the results when there are large and small numbers of molecules available in a finite volume for each protein. Our results for small number of molecules show that with continuous presence of stimulation, nuclear NF- Open image in new window B oscillates continuously in every individual cell rather than damping, which was observed in cell population results. This characteristic of the system is missed when averaged behavior is studied.
