Fig. 1From: Non-linear transformation of enzyme-linked immunosorbent assay (ELISA) measurements allows usage of linear models for data analysisThe eleven serial dilutions used in this trial and the fitted curves. The dual logarithm of the relative concentration is displayed on the X axis, the corresponding OD value is displayed on the Y axis. Blue line: 5PL model, red line: 5PL model with predefined values for top and bottom asymptote, black dots: observed valuesBack to article page
