General description

This plasmid is designed to express tagged proteins in E. coli. The plasmid contains a constitutive promoter (OXB20) derived from the region upstream of the E. coli RecA gene. It does not require induction or any additional components for activity. It is the strongest of the bacterial promoters that we provide and this high level of expression can cause expression problems with some proteins with poor solubility. For this reason we sell a range of bacterial promoters with different expression levels (OXB1(low)>OXB20(high)) that can be provided with the peptide tags in this plasmid on request.

About the Peptide Tag:This plasmid contains an n-terminal V5 epitope tag that can be fused to a gene of interest to allow protein detection and/or purification. The sequence of the tag is: GKPIPNPLLGLDST.

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 3C cleavage tag. The protein sequence of the cleavage tag is: LEVLFQGP. Human Rhinovirus (HRV) 3C Protease is a highly specific protease that cleaves between the Glu and Gly residues of its recognition site. It is often produced with the trademname ′PreScission protease′.

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.
