Abstract
Official abstract text for this publication.
The present invention provides a method for producing a virus vector, which comprises a step wherein cells that are capable of producing a virus vector are cultured in a culture medium that contains, as active components, a retinoic acid and a histone deacetylase inhibiting substance; and a culture medium for the production of a virus vector, which is characterized by containing, as active components, a retinoic acid and a histone deacetylase inhibiting substance.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of producing a retrovirus particle, which comprises a step of culturing a producer cell line which produces the retrovirus particle and producing the retrovirus particle in a culture medium containing retinoic acid and a histone deacetylase inhibitor as active ingredients and a step of harvesting a supernatant containing the retrovirus particle from the culture medium, wherein the culture medium contains either 100 nM to 3 μM trichostatin A or…
