Normally, a cutoff is equal to the mean OD of the negative samples plus 3 standard deviations. The cutoff can be made more robust by adding a higher factor to the mean. stanley turrentine – rough n tumbleWebDon'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. stanley turrentine that\u0027s where it\u0027s at
