■ 質粒簡介
This vector is one of several tightly controlled expression vectors regulated by the arabinose operon. Vectors differ in replicon, antibiotic resistance marker, multiple cloning site and need for translation initiation sequences. Cultures should be grown in minimal media for more reproducible induction of expression. Expression is induced in glycerolcontaining media by the addition of arabinose. Expression is repressed by addition of glucose or other catabolites. Cloned inserts must provide a translation initiation sequence (ATG) and ribosome binding site for expression. Expression of cloned inserts in the two recommended hosts differ in terms of induction characteristics, especially when using low concentrations of inducer (arabinose) and growing in minimal media. The following primers can be used for sequencing of cloned inserts: 5 primer (278bp upstream of the NheI site) :5 CTGTTTCTCCATACCCGTT 3and one of two 3 primers:3 primer 1 (219bp downstream of the HindIII site):5 CTCATCCGCCAAAACAG 33 primer 2 (1733bp downstream of the HindIII site):5 GGCTGAAAATCTTCTCT3
