| |
- |
| |

- | === Chip preparation ===
| |
- |
| |
- | # mix the cooled medium with the cells by inverting gently.
| |
- | # pour it in the chip form, avoiding bubble formation (!).
| |
- | # wait for approximately 20 min until the agar has solidified.
| |
- | # cut out the chips with a scalpel.
| |
- | # put two chips into a labeled petri dish and store additional 4 chips in labeled petri dishs in the refrigerator.
| |
- | # incubate two chips for 1 h at 37 °C prior to induction.

- | ==Run gel==
| |
- | * apply the prepared samples together with a protein marker on the gel
| |
- | * run the gel for 10 min at 60 V and after that for ca. 60 min at 120 V

- | == Bradford assay ==
| |
- |
| |
- | Determination of protein concentration
| |
- |
| |
- | == Measurement of fluorescence ==
| |
- |
| |
- | The measurement of fluorescence was performed using the Synergy Mx (BioTek) microplate reader and the Gen5 software.
| |
- |
| |
- | * volume of sample in each well: 100µl
| |
- | * measure GFP fluorescence at an excitation wavelength of 496 nm and an emission wavelength at 516 nm
| |
- |
| |
- | == Measurement of optical density ==
| |
- |
| |
- | Depending on the number of samples, two different devices were used for measurement of optical density, the Unico Spectrophotometer 1201 (Fisher Bioblock Scientific) and the Synergy Mx (BioTek) microplate reader.
