Analytical Validation of a Highly Quantitative, Sensitive, Accurate, and Reproducible Assay (HERmark<bold><sup>®</sup></bold>) for the Measurement of HER2 Total Protein and HER2 Homodimers in FFPE Breast Cancer Tumor Specimens

<table><i>Precision of the HERmark assay.</i> Fifteen replicates of each of 2 different cell lines spanning the dynamic range of the H2T and H2D assays were run in one batch for each assay to determine intra-assay variability.  95% of the values in the H2T and H2D assay are within 1.45-fold and 1.65-fold, respectively.</table>
