Evaluation of the utility of each spike protein in single donor plasma samples. The mean signal output of (A) CCL6, (B) lungkine, (C) caronte, (D) soggy, (E) luciferase and (F) lysozyme from twelve single donor plasma samples supplemented to comprise the 1× stock of the QC material were determined from three separate experiments with n = 3. The data points denote the mean values for experiment 1 (blue rhombuses), experiment 2 (pink squares) and experiment 3 (green triangles), and the error bars represent the SD.
