Webschild plot requirements for reversible competitive antagonist gradient of 1.0, & intercept @ x-axis = log Kb pA2 affinity of a reversible competitive antagonist is quantified using this: the negative logarithm of the molar concentration of antagonist that produces a dose ratio of 2. p = -log A = [antagonist] 2 = dose ratio WebNational Center for Biotechnology Information

The value can be calculated by using an equation - 日本郵便

WebA Schild plot of these results gave a straight line with a slope of one. The pA2 value obtained by the Schild plot analysis of the data was 8.97±0.25 (Fig. 1 and Table 1). Pilocarpine did not contract this tissue. The drug, however, antagonized the con tractile effect of … WebThe pA2 is defined as the negative common logarithm of B which produces a dose-ratio of 2; hence, pA2 = -log B = -log KB = 10g(1jKB). Since IjKB is the affinity constant, the pA2 may … fábián zoltán

Measure-ments of dose-ratio are commonly used to calculate an an-tagonist equilibrium constant and Schild devised the term pAX to describe log(1/[B]) for a dose-ratio of X, so pA2=7log (KD). It has long been realised, however, that the errors in WebAI Recommended Answer: The slope of a Schild plot is significant because it indicates how much the y-intercept (x-intercept) changes when the x-axis is plotted against the y-axis. If the slope is negative, then the y-intercept decreases as x increases. If the slope is positive, then the y-intercept increases as x increases. fabián villegas ulloa
