Method to produce virus in cultured cells

1. A method for producing a virus comprising:

culturing a host cell infected with a virus under conditions appropriate for producing the virus, wherein:

the conditions include post-infection addition of supplemental fatty acid of at least 20 carbon atoms and a carbonyl and/or a free radical scavenging compound in amounts and for a time effective to improve the amount of virus production compared to virus produced in the method performed without the supplemental fatty acid and scavenger compound.

the addition further includes cholesterol, and

the virus is produced in an amount greater in the presence of the supplemental fatty acid, scavenger and cholesterol compared to virus produced in the method performed without the supplemental fatty acid, scavenger and cholesterol.
