Abstract
In this protocol, small amounts of selected bacterial artificial chromosome (BAC) DNAs are prepared from 5-mL cultures of the Escherichia coli host transformed with the BAC clone. DNA is isolated by an adaptation of the alkaline lysis method. The yield is 0.1-0.4 µg, and the BAC DNA is suitable for analysis by polymerase chain reaction (PCR). Considerations for clone selection are also addressed.
