Viral Vector Development Platforms
Viral vectors are virus-based gene vectors that can be used to deliver target genes into cultured cells or intact living organisms. As a reliable and trustworthy partner, our company has a diverse pool of talent, as well as professional knowledge and experience related to viral vectors. We are committed to using cutting-edge technologies in molecular biology and cell biology to provide comprehensive viral vector development services to our customers for rare disease therapy research and development.
Overview of Viral Vector
Viral vectors can carry genetic material into cells, either in vivo or in vitro. The principle is to use the molecular mechanism of viruses to transmit their genome into other cells for infection. The main types of viral vectors used clinically for in vivo gene therapy include adenovirus, adeno-associated virus (AAV), herpes simplex virus (HSV), retroviruses, and lentiviruses. Viral vectors used for gene therapy and vaccines should meet the following basic conditions:
- Mediates the transfer and expression of foreign genes.
- Don't cause proliferation and spread in the environment.
- Not pathogenic to humans.
- Carry foreign genes and can be packaged into virus particles.

Viral Vector for Rare Diseases
In many cases, gene therapy requires a vector to deliver the gene therapy drug to the target cell. Viral vectors have been one of the most widely studied vectors due to their outstanding transduction efficiency and other significant advantages. Viral vector-based gene therapy has now achieved good clinical results. The following are some of the viral vectors that have been heavily used for gene therapy of rare diseases:
