WebFigure 1: Example of a quantitative ELISA standard curve from Human ICAM1 SimpleStep ELISA® Kit (ab174445). Curve fitting software allow using different models to plot your data.. Linear plot presents the concentration of the antigen in one axis and the readout in the other.R2 values are normally used here to determine fitting, with values higher than … WebDon't use the slope and intercept of a linear regression line to determine values for Bmax and Kd. If you do this, you won't get the most accurate values for Bmax and Kd. The problem is that the transformation distorts the experimental error, so the data on the Scatchard plot do not obey the assumptions of linear regression.

WebThe simplest estimate of IC50 is to plot x-y and fit the data with a straight line ( linear regression ). IC50 value is then estimated using the fitted line, i.e., Y = a * X + b, IC50 = (0.5 - b)/a. Log transformation. Frequently, linear regression is not a good fit to dose-response data. The response-curve fits better to a straight line if the ... WebSelect the two columns in Excel.
