Figure 3From: A pilot study to evaluate the application of a generic protein standard panel for quality control of biomarker detection technologiesEvaluation of the reproducibility of IL-8 detection. IL-8 detection of the twelve single donor plasma samples, are displayed as (A) the mean signal output and as (B) interpolated concentrations of IL-8 from the internal standard curves. These data points (blue rhombuses) are the mean values of triplicate experiments, incorporating triplicate replicate determinants. The error bars denote the SD of the three separate experiments.Back to article page
