The Core uses envelope plasmids encoding VSVG. VSV-G is suitable for experiments involving widespread infection of cells because its phospholipid receptor is universally expressed in mammalian cells and thus has a relatively broad tropism.
While a broad tropism may be suitable for some experiments, others may require higher specificity for infection. The Core is here to advise and provide the resources for your specific needs.
If you would like virus with a coat other than VSV-G, please contact us. Note that different envelope plasmids may yield different titers.
