Hillslope ic50 数值含义
WebFor an enzyme that has no active site cooperativity, the EC50 (we would say IC50) curve of the inhibitor (% inhibition versus inhibitor concentration) should have a Hill slope of 1. If the curve has a Hill slope that is very different from 1 (e.g. 0.5 or 2), it usually means there is a problem with the measurement, such as insolubility of the ...

WebMake sure that your data are normalized to some controls. That means the response at the left end (low concentrations) is near 100%, and the response at higher concentrations is above 0%. If the response plateaus at 0%, then an absolute and relative IC50 are the same, and you can just fit the usual dose-response curve to find the IC50. 2. citizenship churchWebWhen you share these parameters, Prism fits the data sets globally to find one best-fit value for Bottom, Top and HillSlope (for both data sets) and separate best-fit values for the logEC50. 8.
