Expression in bacterial cells. The RecA promoter is a very strong constitutive promoter. It is approximately 650 x stronger than the constitutive AraBAD promoter that we also sell. The RecA promoter is normally regulated by the repressor LexA. In this promoter this binding site has been ablated to enable constitutive expression. This plasmid is used when the T7 terminator and the SV40 poly-adenylation sites that are found within most of our vectors are not required.

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.
