Vector containing primer sites useful for sequencing
Vector permitting visual detection of recombinants
Comments
Restriction digests of the clone give the following sizes (kb): EcoRI--5.6; HindIII--5.6; PstI--5.6.
After mobilization, the plasmid can be maintained by integration into the host chromosome via homologous recombination.
Excision of the intervening plasmid sequence by a double cross-over event can be faciliated by selection on medium containing 10 percent sucrose.
The sacB gene has been modified to eliminate the HindIII and EcoRI sites in the coding region.
Differs from pK18mobsacB (ATCC 87097) only in the orientation of the polylinker.
Cloning vector allowing mobilization into a wide range of Gram- and Gram+ bacteria.
