Please suggest a protocol for the safe handling of adenovirus for a person having chemistry background who is planning to use it for gene therapy by conjugating polymers ?
If you are not collaborating with someone who is quite familiar with biological research involving the use of recombinant virus, I would recommend that you begin with contacting the "Biological Safety" office in your institution.
Treating everything as if it is an infective and self-replicating virus is a good and safe strategy - but you must learn many aspects of this work that are related to safety - your's, your colleagues' and the environment.
Where are you located; are you by any chance in Pécs?
If you cannot find anyone locally, which I highly doubt, and if you are in Pécs, I could put you in touch with an old friend, Balazs Sümegi, who may be helpful.
