Size (kb): 2.7160000801086430
Vector: pOM2 (plasmid)
Promoters: Promoter lac
Construction: pUC8, M13tg131
Construct size (kb): 2.716000080108643
Features: insert detection: lacZ'
vector containing primer sites useful for sequencing
vector for constructing cDNA libraries
vector permitting visual detection of recombinants
Restriction digests of the clone give the following sizes (kb): PstI--2.7; HindIII--2.7; EcoRI--2.7; XhoI--2.7.
Escherichia coli transformed with this plasmid produce larger colonies when an insert is present in the polylinker than when there is no insert.
Expression vector useful for construction of cDNA libraries and containing priming sites useful for sequencing. Permits visual detection of recombinants by beta-galactosidase alpha peptide complementation.
pOM1 (ATCC 77220)
and pOM2 (ATCC 77221)
differ in the orientation of the polylinker.
