Figure 5

Comparison of a standard curve of innovator vancomycin with samples containing 10% (red), 15% (blue) and 20% (green) more antibiotic. The curve fitting analysis showed no difference in slopes (i.e. all samples had the same biological activity) but significantly different intercept (i.e. more concentration) in the 20% group (indicating the threshold for statistical significance of the assay).
