WebED50とは、用量反応滴定において最大用量の50%を生じるのに必要なタンパク質の濃度のことです。 ED50による評価は、以下の図のように、50%濃度値が容易に識別可能なシグモイド活性曲線を持つタンパク質に最も適しています。 ED50は実験の出発点になりますが、ユーザーは依然として自分のアッセイに最適な濃度(さらにはED50)を見つける必要 … The EC50 relates to the Hill equation, which is a function of the agonist concentration, [A]: where E is the observed response or effect above baseline, and nH, the Hill coefficient reflects the slope of the curve. The EC50 represents the point of inflection of the Hill equation, beyond which increases of [A] have less impact on E. In dose response curves, the logarithm of [A] is often taken, turning the Hill eq…
WebEC 50 or the concentration of antibody that gives half-maximal binding is determined by direct and saturable binding of a rAB dilution series to both target antigen and a non-specific control protein. An estimate of affinity is interpreted from one-half the concentration at which rAB binding first achieves saturation.
