Additional file 4: of Robustness of biomarker determination in breast cancer by RT-qPCR: impact of tumor cell content, DCIS and non-neoplastic breast tissue

Mammatyper® relative gene expression and Δ40-ddCq values are shown for the effect of DCIS. Tumor cell content, DCIS content, HER2 immunohistochemical score of the invasive tumor and the DCIS, as well as relative expression of the mRNA markers ERBB2, ESR1, PGR and MKI67 and absolute Δ40-ddCq values are shown.
