Adenoviruses can be concentrated to high titers of 10^11 IU/ml making them an extremely efficient method of delivering shRNA or transgenes in vivo.
Additional benefits for in vivo use are the fast and strong onset of expression.
When using adenoviruses one must take into consideration that >90% of the virus particles will be absorbed by the liver and that there can be strong immunoreactions of the host organism.
BL-2 (S2) facilities are required when handling adenoviruses.

Fields of Application
