The Virus Platform provides packaging services for a variety of viral types including retrovirus, lentivirus, adenovirus, adeno-associated virus (AAV). The viral titer and purity are guaranteed for effective infection for both cultured cells and tissues. The lead time for virus packaging ranges from 1 month to 3 months.

Lentivirus is a genus of slow viruses of the Retroviridae family, characterized by a long incubation period. Lentiviruses can deliver a significant amount of genetic information into the DNA of the host cell and have the unique ability among retroviruses of being able to replicate in non-dividing cells, so they are one of the most efficient methods of a gene delivery vector. Like many other types of retroviruses, lentivirus is an excellent research tool for stable introduction of a gene product into in vitro systems or animal models for stable expression. The titer of packagede lentiruses ranges from 1x10⁶ to 1x10⁸ TU/ml.
