WebThe Scatchard equation is given by By plotting n / [ L] versus n, the Scatchard plot shows that the slope equals to -1/ Kd while the x-intercept equals the number of ligand binding … Web4. Plot the data on a Scatchard Plot: From the saturation equation, the following rearrangement can be made to give a useful analytical tool, the Scatchard equation: † Y [L] =-1 KD Y+ 1 KD A plot of Y/[L] versus Y will give a straight line with a slope of –1/KD. This is a useful transformation of the original hyperbolic binding curve to a ...
WebHill Plots Are Used When Scatchard Plots Are Not Linear. Hill plots define a saturation fraction, ν, which is the amount of bound ligand divided by the number of binding sites: … WebHill analysis A method for analysing saturation or competition curves to determine whether the interaction between the ligand and the receptor is competitive. As with the Scatchard plot, the Hill plot has now largely been superseded by computer- fitting of the curves to a one- or multi-site model.

We advise against using linear regression to produce the Web1 day ago · The Scatchard plot is better than the Eadie–Hoffstee plot for binding data because it depends more on the values at high ligand concentration, the most reliable values. Nonlinearity can arise through heterogeneity of receptors, although there are other possible causes. From: Scatchard plot in A Dictionary of Biomedicine »
WebScatchard plots Before nonlinear regression programs were widely available, scientists transformed data to make a linear graph, and then analyzed the trans- formed data with linear regression. There are several ways to linearize binding data, but Scatchard plots (more accurately attributed to Rosen- thal) are used most often.
