Figure 1From: Epstein-Barr virus infection and clinical outcome in breast cancer patients correlate with immune cell TNF-α/IFN-γ response Quantification of EBV DNA in peripheral blood mononuclear cells (number of copies/μg) from the 85 BC patients. The detection threshold was 5 and 10 copies EBV DNA/μg for PBMCs and tumor biopsies, respectively. Comparison with EBV load in tumors (number of copies/μg) (A) and with anti-ZEBRA antibody titers (in absorbance of 450 nm) (B) (an optical density of 1 corresponds to a titer of 1000).Back to article page
