Webb24 feb. 2024 · You are dealing with normalized data, but compounds may be either inhibitors (0% to 100% inhibition), or activators (-100% to 0% inhibition) so the range of activity will be from -100% to 100%, and EC50 can be at -50% or 50% The activity threshold would be set from -50 to 50%. Webb1 mars 2011 · The absolute EC50/IC50 should only be used if there are at least two assay concentrations whose predicted response is less than 50% and two whose predicted response is greater than 50%.

This is a very challenging problem, however, and even with MD simulations it is difficult to obtain absolute binding energies. Also, IC50 values are dependent on the conditions in which they are measured, so it's not possible to state a … Webbمقياس Pic50. تقيس قيمة التركيز التثبيطي الأقصى حتى النصف (IC50) فعالية تثبيط المُركب تجاه المنفعة البيولوجية أو الكيميائية الحيوية. ويشير القياس الكمي إلى الكمية المطلوبة لمُثبِّط معين لتثبيط ... rebecca tsang northshore
