WebOn Hill coefficients and subunit interaction energies Hagai Abeliovich 1 , 2 Received: 7 June 2015 / Revised: 29 February 2016 / Published online: 1 April 2016 WebA HillSlope of 1.0 is standard, and you should consider constraining the Hill Slope to a constant value of 1.0. A Hill slope greater than 1.0 is steeper, and a Hill slope less than 1.0 is shallower. Baseline is the measured response of a "standard" drug or control resulting in a maximally inhibited response. This value must be entered by the ...

WebA dose–response curve is a coordinate graph relating the magnitude of a dose (stimulus) to the response of a biological system. A number of effects (or endpoints) can be studied. The applied dose is generally plotted on the X axis and the response is plotted on the Y axis. In some cases, it is the logarithm of the dose that is plotted on the ... WebThis variable is called the Hill slope, the slope factor, or the Hill coefficient. If it is positive, the curve increases as X increases. If it is negative, the curve decreases as X increases. A standard sigmoid dose-response curve (previous equation) has a Hill Slope of 1.0. When HillSlope is less than 1.0, the curve is more shallow.
WebThis is positive cooperativity. You can have a Hill coefficient that is as large as the number of subunits available, though just because you have 4 subunits doesn't necessarily mean the coefficient is 4. Just that it can't be any higher than that. If binding to one subunit makes it harder for other subunits to bind, that's negative cooperativity. WebA general empiric definition for a Hill coefficient (n(H)) for channel gating transitions that is analogous to the logarithmic potential sensitivity function of Almers is derived. This definition provides a novel framework for interpreting the meaning of the Hill coefficient. In considering three particular and simple gating schemes for a ...
