Effect of long-term storage at different temperatures on HEV stability. An HEV-containing liver suspension was incubated at 4°C (A), 22°C (B) or 37°C (C) for up to 70 days and protected RNA was quantified using real-time RT-PCR. The resulting data were used for fitting of a curve using a biphasic model according to Cerf, 1977 (29).
