J23106a:Improved promoter of J23106

J23106a is a constitutive promoter obtained by mutating <a url="https://parts.igem.org/Part:BBa_J23106"> J23106</a>. The strength of this promoter is much weaker than J23106.


Functional Parameters

To characterize this part, J23106a and J23106 were cloned into pSC101 vector separately. We chose <a url="https://parts.igem.org/Part:BBa_K3733012">neGFP </a> as the reporter. Plasmids were transferred into E.coli DH5α. The E. coli strain was cultured overnight, and the relative intensity of J23106a was evaluated by measuring RFU/OD600 under the control of two different promoters. The relative fluorescence unit (RFU) was determined by Synergy H1 microplate reader.
