2020-08-17 19:53 Introducing new genetic material into target cells without causing toxicity to non-target tissues is the goal of cancer gene therapy. The adeno-associated virus (AAV) is a small virus that allows packaging of only 4 kb inserts. AAV has low toxicity, apparent lack of pathogenicity and provides long-term transgene expression through chromosomal integration. Using the basic principles of molecular biology and laboratory techniques, Creative Biolabs provides a wide variety of AAV vectors for both basic research and clinical applications.
