Why Use AAV or Adenovirus

AAV and adenoviruses are powerful gene delivery tools and are similar in that both integrate into the host cell episomally.

Product Differentiation

AAV

What is Adeno-Associated Virus (AAV)?
Adeno-Associated Virus (AAV) is a safe, non-pathogenic virus used for gene delivery in research and therapy. It effectively targets diverse tissues, providing long-term gene expression with minimal risk of genetic mutations.

Adenovirus

What is Adenovirus?
Adenovirus is a robust viral vector capable of delivering large genes, ideal for various research and therapy uses. It infects a wide range of cell types and provides high short-term gene expression.
