Arabinose inducible GFP (pBAD+GFP)

A GFP reporter under control of a pBAD promoter, used to characterise the activation range of the pBAD promoter

Usage and Biology

Without any arabinose in the cell, araC forms a homodimer, binding to operator sites upstream of the pBAD promoter, generating an inhibitory loop in the DNA that prevents access by the RNAP holoenzyme. In the absence of glucose, and the presence of L-arabinose, the dimer dissociates from the DNA, allowing transcription of GFP.

We added varying concentrations of arabinose (optimum concentration ranges were obtained from (sloveniaon igem characterisation), and recorded fluorescence in a BMG plate reader.
