Pseudotyped Viral Vector Development Platform

Pseudotyped viral vector has become an effective tool for the delivery of therapeutic genes to target cells in gene therapy due to their unique properties including very broad tropism, high biosafety, and stability. Our company is committed to providing customers with pseudotyped virus vector development services to develop effective novel gene transfer vectors to accelerate the development of gene therapies for rare diseases.

What are Pseudotyped Viruses?

Pseudotyped viruses are viral particles that are encapsulated in other enveloped viral glycoproteins, but their cellular and histophilic properties are determined by the encapsulated glycoproteins. Pseudotyped viruses have been shown to be a novel gene transfer vector with the advantages of non-cell cycle-dependent integration, easier concentration into high titers than proto-viruses, broad tropism, and safe and efficient transfection of cells, which provides a new way to solve the key problem of vector systems in gene therapy.

Applications of Pseudotyped Viral Vectors

Different viral vectors such as retroviruses have a natural host cell population that they can effectively infect but are limited in scope. While adeno-associated viruses (AAV) can infect a relatively wide range of cell types, the difficulty in infecting certain specific cell types limits their use in gene therapy. Limiting or expanding the range of cells sensitive to transduction by gene therapy vectors is essential for the development of effective gene therapies. The development of pseudotyped viruse vectors of enveloped viruses offers an attractive approach to the problem of gene delivery.

Our Services
