| − | | + | |
| − | PBad promoter from I0500 without AraC.
| + | |
| − | | + | |
| − | | + | |
| − | ===Usage and Biology===
| + | |
| − | | + | |
| − | Has been used as a second promoter in a system containing <partinfo>I0500</partinfo> (PBad+AraC). In this system, it showed behavior qualitatively indistinguishable from the <partinfo>I0500</partinfo> copy of PBad. Has not been tested independent of AraC. A second part, <partinfo>I13458</partinfo>, should allow decoupling of PBad and AraC.

| + | |
| − | For the 2009 iGEM competition, British_Columbia characterized <partinfo>I13453</partinfo> in the context of a [https://parts.igem.org/PBAD_Promoter_Family pBAD promoter family]. For the results of this characterization, see [[Part:BBa_I13453:British_Columbia|here]].
| + | |
| − | | + | |
| − | For the 2010 iGEM competition, Tec-Monterrey characterized <partinfo>I13453</partinfo> again, using a construct of GFP reporter after the pBad promoter. The transfer function was modeled with a Hill equation.

| − | | + | |
