Comments
Restriction digests of the clone give the following sizes (kb): EcoRI--5.4; HindIII--3.9, 1.5; PstI--5.4.

Cultures should be grown in minimal media for more reproducible induction of expression. Expression is induced in glycerol-containing media by addition of arabinose. Expression is repressed by addition of glucose or other catabolites.

One of several tightly controlled expression vectors (ATCC® 87393-87402™) regulated by the arabinose operon. The vectors differ in replicon, antibiotic resistance marker, multiple cloning site and mechanism of initiation of translation.

The following primers can be used for sequencing of cloned inserts: 5' primer (27 - 8 bp upstream of the NheI site) 5'-CTGTTTCTCCATACCCGTT-3'; and one of two 3' primers: 3' primer 1 (2 - 19 bp downstream of the HindIII site) 5'-CTCATCCGCCAAAACAG-3';

3' primer 2 (17 - 33 bp downstream of the HindIII site) 5'-GGCTGAAAATCTTCTCT-3'.

Cloned inserts must provide a translation initiation sequence (ATG) and ribosome binding site for expression.

Plasmid contains bla (ampR) sequences surrounding the kanR gene which could promoter recombination if this plasmid is used in combination with other compatible ampR plasmids.

Recombination can be avoided by the use of recA host strains, or it can be used to advantage to intentionally exchange markers among plasmids.
