Results: Part Characterization using Flow Cytometry
After being integrated into the yeast genome, parts were characterized individually by flow cytometry.
TALEs
- Initial characterization: TALE-mCherry constructs are present and expression is inducible by β-estradiol. Cells were grown with and without β-estradiol and fluorescence was compared to background levels using a control strain.

- Relationship between beta-estradiol concentration and TALE-mCherry expression. Cells were grown in varied β-estradiol concentrations and fluorescence was compared to background levels using a control strain

ACT1 reporters
- Initial characterization: ACT1-yEVenus constructs with no operators showed distinct constitutive gene expression. However, presence of operator sites in the 5' UTR knocked down constitutive expression almost to background levels. In lieu of these results, we decided to construct TEF1-promoter reporter constructs. TEF1 is a stronger constitutive promoter that we hoped would counteract the effects of the operator sequence on constitutive expression levels.

TEF1 reporters
- Initial characterization: TEF1-yEVenus constructs with operator sites in the 5' UTR showed expression levels significantly higher than background levels, and comparatively higher than the ACT1-yEVenus constructs.
