General description
About the Peptide Tag:This plasmid contains an n-terminal Hexa-Histidine (6His) affinity tag that can be fused to a gene of interest to allow protein detection and/or purification. The sequence of the tag is: HHHHHH. This plasmid also contains a secondary Flag protein tag. The sequence of this tag is: DYKDDDDKWe provide a range of dual peptide tag plasmids. This is because some peptide tags provide specific biological properties (e. g., small molecule affinity new epitopes solubility or protein secretion) that are not provided by others.
About the Cleavage Tag: This plasmid also encodes a protease cleavage site that is designed to be positioned between your gene of interest and the tag to allow the removal of the tag following protein purification or isolation. This plasmid contains a EKT cleavage tag. The protein sequence of the cleavage tag is: DDDDK. Enterokinase (EKT) protease cleaves after the Lysine residue. It can cleave at other basic residues but this is dependent on protein confirmation. If a proline follows the site it will not cut. None of our products contain a proline after the site.
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.

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.
