WebThe only source of non-linearity in this model is a Hill function, characterizing the repression process. It was mathematically shown that to obtain limit-cycle oscillations, the Hill coefficient must be larger than 8, a value often considered unrealistic. It is indeed difficult to explain such a high coefficient with simple cooperative dynamics. WebHalf maximal effective concentration ( EC50) is a measure of the concentration of a drug, antibody or toxicant which induces a response halfway between the baseline and maximum after a specified exposure time.
