I've been wanting to know how long I can store the virus at 4 deg. I've seen that most people quote days, would a week be ok? Has anyone seen any decreases in titre of their virus when stored for this amount of time at this temperature?
I've only been storing my virus for this long at this temperature becuase I was producing quite a lot of virus and wanted to wait for production to finish before I concentrated the virus and then froze these down. I've heard that each freeze/thaw cycle may decrease titre/infectivity by 20-50% so wanted to avoid any freeze thaws until concentration and subsequent use.
