Patent number: 6864087Abstract: A single-copy BAC vector (containing or lacking an insert) is converted in a host cell into a conditional high-copy BAC vector by introducing a conditional origin of replication into the single-copy BAC vector. The conditional ori is introduced by site-specific recombination between the SC BAC vector and a vector that contains the conditional ori. The host cell comprises a recombinase that recognizes a site-specific recombination site on both the BAC vector and the conditional ori vector. In the presence of the recombinase, the conditional ori-containing vector recombines into the BAC vector to produce a high-copy BAC vector that can be conditionally amplified by activating the conditional origin of replication on command.Type: GrantFiled: July 31, 2002Date of Patent: March 8, 2005Assignee: Wisconsin Alumni Research FoundationInventors: Waclaw Szybalski, Jadwiga Wild, Zdenka Hradecna
