sfGFP-LVAtag expression casette under the control of J23110 promoter

This part is an sfGFP-LVAtag (BBa_K2675006) expression cassette under the control of the constitutive promoter BBa_J23110.

Usage and Biology

In this composite part sfGFP-LVAtag (BBa_K2675006) was equipped by a custom made RBS (BBa_K2675017) and placed under the control of the constitutive promoter (BBa_J23110).

The pictures of E. coli cells harbouring this part show a very strong sfGFP-LVAtag expression. In contrast, no sfGFP-LVAtag is observed in the absence of the promoter and the RBS (BBa_K2675081).

Figure 1. Pictures of E. coli cells harbouring an empty pSB1C3 backbone, BBa_K2675081 or this part BBa_K2675056.

We used this part as a positive control of sfGFP-LVAtag expression and as a negative control of promoter regulation.
