Virus Safe Deposit icon

Safe storage of valuable virus stocks for future use is often of paramount importance! A virus safe deposit can put your mind at rest.


OET offers a comprehensive virus safe deposit facility, with an accompanying expression testing service. Initially we will produce a batch of high titre virus inoculum. This will then be titrated by plaque assay and expression tested by Western blot. Forty virus ampoules will then be prepared for –80°C storage and twenty of these sent to ECACC (European Collection of Cell Cultures) for long-term safe storage. The remaining twenty samples will be stored at OET. One frozen ampoule of the virus will then be retrieved after one month’s storage, thawed and the virus titrated by plaque assay. Protein expression will then be confirmed by Western blot.


The samples are stored, and expression tested on a yearly basis. Contact our trusted team to find out more.
