Figure 2. Percentage of neutralization against genotype 1a and 1b culture viruses in 39 patients with chronic HCV, genotype 1, infection.

Figure 2

Plasma samples from 39 patients, taken prior to treatment initiation with pegylated interferon-α and ribavirin, were tested against genotype 1a Core-NS2 recombinants (TN/JFH1, DH6/JFH1, and H77/JFH1) and genotype 1b Core-NS2 recombinants (DH1/JFH1, DH5/JFH1, and J4/JFH1). The graph shows the percentage of neutralization in the samples at a 1∶50 dilution. Results are correlated with treatment outcome (SVR, Non-SVR) and each dot represents a patient. Dots located at the x-axis neutralized the culture virus ≤0%. For each group the mean is marked with a line.
