Abstract excerpt
The lack of safe and effective delivery vectors continues to be a critical limitation facing human gene therapy. Viruses offer excellent efficiency but can be difficult and expensive to produce and purify. For example, the production and efficiency of murine leukemia virus (MLV) are limited by its inherent instability; the half-life of infectivity is 5-8 hours at 37 degrees C. In order to generate a stable MLV,...
