Part:BBa_K3885351

P28-tetO-deGFP

Under the P28 promoter, the Tet operator tetO is expressed along with the production of green fluorescent protein.

Usage and Biology

1.This plasmid has no label ssrA . We use it to investigate the effect of degradation label ssrA on deGFP fluorescent protein.
2.Provide tetO to binding repressor protein and inhibit the production of fluorescent protein.
3.It can be used in other experiments which hope to express fluorescence.

Characterization

This part was mainly combined with tetR to verify its success in suppressing the expression of deGFP. By electroporation of BW25113 and plasmid containing P70-σ28-P28-tetR as well as plasmid containing P28-tetO-deGFP, it was verified that tetR could inhibit the expression of deGFP successfully.

The results showed that there was a significant difference between the group containing the element and the control group, which proved that the element could perform the expected function, that is, tetR could normally express the repressor protein to inhibit the intensity of deGFP.
