5. Data is expressed as percentage neutralisation; this was calculated by<br />
comparison <strong>of</strong> the level <strong>of</strong> <strong>in</strong>fection after <strong>in</strong>hibitory treatment to that<br />
after treatment with a control compound.<br />
Statistical analysis <strong>of</strong> <strong>in</strong>fectivity data.<br />
To ensure appropriate statistical analysis <strong>of</strong> <strong>in</strong>fection assays we used a<br />
D'Agost<strong>in</strong>o & Pearson omnibus normality test to determ<strong>in</strong>e whether typical<br />
<strong>in</strong>fectivity data fits a Gaussian distribution. Briefly, the data from n=10 JFH-1<br />
and J6/JFH-1 HCVcc <strong>in</strong>fection assays were analysed us<strong>in</strong>g GraphPad Prism<br />
(GraphPad S<strong>of</strong>tware, CA, USA), both data sets were deemed to be normally<br />
distributed as summarised <strong>in</strong> Table 2-5. We therefore have assumed normal<br />
distribution for all <strong>in</strong>fectivity data and statistical analyses were performed<br />
us<strong>in</strong>g an unpaired t-test.<br />

Iodixanol density gradient centrifugation.<br />
<strong>The</strong> analysis <strong>of</strong> HCVcc particle density was achieved by iodixanol density<br />
gradient centrifugation. This work was carried out <strong>in</strong> collaboration with Dr<br />
Søren Nielsen <strong>of</strong> Newcastle University Medical School. <strong>The</strong> preparation and
