An Efficient Method for Isolation of Plasmid DNA for Transfection of Mammalian Cell Cultures

In this article, we present several protocols that describe the steps from cloning and obtaining a large amount of pure plasmid DNA to generation of lentiviruses based on these constructs. The protocols have been worked out on human cell culture HEK293T but can be adapted for other cell cultures. This protocol was designed to be simple to execute and cheap since it requires only materials and consumables widely available in molecular laboratories, such as salts, alcohols, etc., and no complicated laboratory equipment. These protocols are highly effective and can be performed in any standard molecular biology laboratory.
