Characterization

For this experiment the cell grew in the 30ºC chamber with shaking until they reached OD of around 0.4 (spechtophotometre indicated that the OD was 0.4, the TECAN in which the fluorescence was read says 0.2 in the beginning, but this OD is irrelevant since the values only matter for normalization). When the OD was reached, induction with the indicated concentrations of IPTG was made, the culture was put into a 96-wells plate, and measured on the TECAN for 1hour. (Note, the measure was made without shaking) These are the results that the TECAN automatically provides.

For this experiment the cell grew in the 30ºC chamber with shaking until they reached OD of around 0.4 (spechtophotometre indicated that the OD was 0.4, the TECAN in which the fluorescence was read says it is 0.2 in the beginning, but this OD is irrelevant since the values only matter for normalization). When the OD was reached, induction with the indicated concentrations of IPTG was made, the culture was putted back in the 30'C chamber with shaking. Timepoints was taken and measured directly in the TECAN. These are the results. Values for graph without correction of OD600

Values for graph normalizing with OD600

5h Long washed with water The experiment was repeated because LB emits fluorescence at the same range as GFP. This time it was done like this: For this experiment the cell grows in the 30ºC chamber with shaking until they reached OD of around 0.4 (spechtophotometre indicated that the OD was 0.4, the TECAN in which the fluorescence was read says 0.2 in the beginning, but this OD is irrelevant since the values only matter for normalisation). When the OD was reached, induction with the indicated concentrations of IPTG was made and the culture was putted back in the 30'C chamber with shaking. Timepoints was taken, washed them with water and measured them directly in the TECAN IN WATER These are the results.
