This plasmid contains a very strong constitutive bacterial promoter that can be used to produce proteins in E. coli. The promoter was developed by making modifications to the E. coli LacUV5 promoter to remove the LacO repressor binding site. It is the second strongest in our product range of E. coli promoters with OXB1 being the weakest and OBX20 being the strongest. It does not require induction for activity.

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.
