Figure 1From: Deep sequencing of hepatitis C virus hypervariable region 1 reveals no correlation between genetic heterogeneity and antiviral treatment outcome Frequencies of erroneous variants obtained from sequencing of a single HVR1 clone. Control experiment performed by sequencing a single HVR1 clone from one pretreatment serum sample presented 11 erroneous variants at frequency between 1.48% and 0.06%. The figure reports, in decreasing order, the frequencies of all 11 variants.Back to article page
