Plasmid: pDO193


Plasmid Type
Cloning Method
Restriction digests of the clone give the following sizes (kb): EcoRI--7.0; HindIII--7.0; NdeI--7.0; BglI--4.8, 2.2. (ATCC staff) Plasmid contains the following restriction sites (approximate kb from nt 1): BamHI--3.10; BglI--3.29, 5.37; EcoRI--3.06; HindIII--3.14; NdeI--4.19; PstI--0.65, 5.50; PvuI--3.26, 5.62; SacI--3.11; SmaI--3.11; XbaI--2.11. (GenBank/EMBL/DDBJ) Cosmid vector containing two compatible origins of replication, for generating bidirectional deletions of large inserts to facilitate sequencing. A series of overlapping deletion segments can be generated by cutting at the Cos site with lambda terminase, then filling in ends with a alpha phosphorothioate nucleotides, cutting with a restriction enzyme that cuts on one side of the insert, and then digesting with Exo III for various intervals of time. Resulting fragments are blunted and circularized by ligation, and transformants are selected for either ampicillin or kanamycin resistance. AmpR transformants can be sequenced in the clockwise direction using the cosL primer 5'-TCATAAATAGCGAAAACC-3'. KanR transformants can be sequenced in the counterclockwise direction using the cosR primer 5'-ACTTTACGGGTCCTTTCCG-3'. [2] The order of the major features in the plasmid is: 3' lacZ - HindIII/MCS/EcoRI - 5' lacZ - ori 15 - kanR - cosR/L - ampR - oriP. pDO193 contains 2 groups of sites recognized by 8 bp cutters separated by a cluster of common restriction sites in the polylinker. Growth: 1065 plus ampicillin (50 ug/ml) plus kanamycin (20 ug/ml) 30C Deposited by: Ahmed A.L. Hosts: E.coli, E.coli AA102. (Information source: VectorDB ( ).)
