Description_x000D_ General description_x000D_ This vector is a standard E. coli expression plasmid with the exception that it has been modified to allow the direct cloning of gene fragments that have been designed to fit with any of our peptide tag plasmid range. This can be useful if you have created a peptide fusion but you would also like to create a non-tagged gene variant. The multiple cloning site contains two BsgI and BseRI sIt`s that produce overhangs that are compatible with gene designed using our SnapFusion primer designer (see the cloning tab for this product). The promoter in this plasmid is a strong constitutive bacterial promoter that does not require induction for activity._x000D_ Promoter Expression Level: This plasmid contains a very strong constitutive E. coli promoter that was derived from the RecA promoter by removing the LexA repressor site. It is part of our constitutive bacterial promoter range. This promoter shows the highest level of expression in the promoter range with OXB1 showing the lowest level. They require no inducing agent for expression._x000D_ Sequence_x000D_ Quick-reference Plasmid Map_x000D_ Please select the file type you require.
