Please provide the positive control(s) you used.
BBa_I20270
Please provide the negative control(s) you used.
Untransformed for both strains Transformed with BBa_R0040 (ptetR in pSB1C3)
What type of agar did you use?
LB Agar with 30µg/mL chloramphenicol
Workflow
- Streak out 1 plate per device and control
- Incubate plates for 17h at 37 C
- Inoculate test tube with with dimension (WxH) of 16 x 1.3 cm and 5mL LB-medium 30µg/mL chloramphenicol
- Incubate test tubes for 8h in incubator with 220 rpm at 37°C
- For the 10°C samples: transfer them to 10°C incubator
- For the 37°C samples: shake another 8 h in 37°C incubator
- Set your instrument to read OD600
- Measure each sample in cuvette
- Take the measurement and record it
- Measure OD600 of all samples
- Calculate the dilution required for each sample
- Dilute each sample
- Re-measure your sample on OD600
- If your OD600 is within 5% of 0.5, proceed
- If your OD600 is outside that range, recalculate your dilution and remeasure until it's within the range of +/- 5%
- set up sodium fluoresceine standard curve with 500, 375, 250, 125, 50, 25, 10, 5 and 0 ng/mL concentration
- pipette the samples and the standard curve in 96-well plates (triplicates)
- measure emission at 530 nm after excitation at 485 nm
