4. After EP the cells were allowed to stand for 5 m<strong>in</strong>s at RT prior to be<strong>in</strong>g<br />
transferred <strong>in</strong>to 10ml <strong>of</strong> pre-warmed DMEM + 10% FCS + P/S. 8ml <strong>of</strong><br />
the resuspended cells were placed <strong>in</strong> a T75 culture flask, and the<br />
rema<strong>in</strong>der put <strong>in</strong>to 2 wells <strong>of</strong> a 24 well tissue culture plate to allow the<br />
monitor<strong>in</strong>g <strong>of</strong> HCV prote<strong>in</strong> expression. <strong>The</strong> cells were immediately<br />
taken <strong>in</strong>to category 3 conta<strong>in</strong>ment laboratories for culture and harvest<br />
<strong>of</strong> particles.<br />
5. At 48 hrs post EP, the efficiency <strong>of</strong> viral replication was quantified by<br />
detection <strong>of</strong> the HCV non-structural prote<strong>in</strong> NS5A. Briefly,<br />
electroporated cells were sta<strong>in</strong>ed us<strong>in</strong>g the immun<strong>of</strong>luorescence (IF)<br />
protocol with sapon<strong>in</strong> permeablisation (as detailed above), mouse anti-<br />
NS5A mAb 9E10 was used at 1/200 dilution. JFH <strong>in</strong>fected NS5A<br />
positive Huh-7.5 cells are shown <strong>in</strong> Figure 2-2.<br />
6. HCVcc particles were harvested between 4 and 14 days post EP, after<br />
which the cells were discarded. To harvest, <strong>in</strong>fected cells were cultured<br />
<strong>in</strong> a m<strong>in</strong>imal volume <strong>of</strong> DMEM + 3% FCS + P/S and media conta<strong>in</strong><strong>in</strong>g<br />
secreted virions collected every 8-14 hrs. Harvested virus was frozen<br />
prior to titration us<strong>in</strong>g the <strong>in</strong>fection assay.
