Testing of S. aureus sensing pathway
(Transformant with pNZ8148 harboring BBa_K2309005):
- Grow 5 ml successfully transformed bacteria culture overnight, 30 °C.
- Dilute 1/25 in 2 x 10 ml fresh medium (30 °C). Grow until the OD600 ≈ 0.4.
- Induce one 10 ml culture with 0.5 - 5 ng/ml nisin (typically 1 ng/ml is used) and keep the other 10 ml culture as negative control.
- Incubate 2 - 3 hours
- Aliquot both control group and experiment group into 96-well plate.
- Test the fluorescence under the set of 485 nm excitation and 510 nm emission.
