  • Patent number: 7943303
    Abstract: Methods are provided for engineering novel strand-specific nicking endonucleases by means of an in vivo enrichment of a plasmid library containing a randomly mutagenized restriction endonuclease gene. The plasmids contain adjacent to the gene a cleavable or nickable sequence for cleaving or nicking by the endonuclease product of the gene and a second recognition site for a second endonuclease. The plasmid library is used to transform unmodified host cells. Plasmids from the cultured transformed cells may be analyzed by an in vitro assay for nicking and the nicked plasmids pooled and used to transform host cells. The product is then pooled and the single-stranded specificity of the endonuclease is then determined. The product is either cloned after amplification or identified by use of a selectable marker.

  • Patent number: 6864087
    Abstract: 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.
