Adenovirus

SIRION Biotech`s inducible expression platform is based on the latest 3G TET technology. This guarantees a highly sensitive doxycycline-inducible system without leakiness. Our inducible adenovirus platform is based on a TWO vector system.

Fields of Application

Benefits

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.

An alternative for in vivo injections with versatile and highest tissue tropism, minimal immunogenicity and handling under BL-1 (S1) are AAVs.
