Vector backbonepBAD TOPO
- Backbone size w/o insert (bp) 4127
Vector typeBacterial Expression
Growth in Bacteria
Bacterial Resistance(s)Ampicillin, 100 μg/mL
Growth Strain(s)XL1 Blue
Growth instructionsGrow E. coli to early-log phase (OD600 = 0.3 ~ 0.4) in 50 mL of LB medium in a shaking incubator at 33 C. Add inducer along with all-trans retinal (5 microM from a 20 mM stock in ethanol) and conduct further growth in the dark. Harvest cells after 3.5 hours and wash with 30 mL of minimal medium (1x M9 salts, 0.4% glucose, pH 7). Resuspend cells in 5 mL minimal medium and use immediately or store at 4 C for later use.
