General description
Promoter Expression Level: This plasmid contains a constitutive bacterial promoter that does not require induction. It is the strongest bacterial promoter we sell and this can cause solubility and expression problems with some proteins. We also offer a range of other bacterial promoters that are compatible with this plasmid and are available on request.
Application
By positioning all of our genes in the same location it allows them to be transferred between plasmids using the same cloning method and restriction sites regardless of the plasmid being used from our product range. Inserting a new gene into this plasmid should be easily possible using a range of standard restriction enzyme sites that flank the gene currently in the vector.
Multiple cloning site notes: In the multiple cloning site there are two important restriction sites called BsgI and BseRI sites. These sites both cut the DNA at the same position and cleave the stop codon of the gene in the multiple cloning site in this plasmid thereby producing a TA overhang. This overhang is compatible with any of our peptide or reporter fusion tag plasmids also cut with either of these enzymes. This allows seamless C-terminal fusions to be made with the gene in this multiple cloning site using a single cloning step from our C-terminal peptide and reporter tag product range. Normally the easiest method is to clone the C-terminal tag from our other plasmid products into this plasmid using BsgI or BseRI and the downstream ClaI restriction site.
BseRI and BsgI sites are non-palindromic and cleave a defined number of bases away from their binding sites. This allows them to cut the upstream stop codon in the gene in this plasmid regardless of the gene sequence.

A range of forward and reverse sequencing primers that allow you to sequence any insert that you make into a particular position within any plasmid. Where possible, the binding sites for each of these primers is conserved.
Our plasmids are composed of both a core vector backbone and a series of DNA components. Our plasmid platform is all built around the same core backbone, which means that the DNA components within each plasmids can be interchanged into each other.
