Discussion
It can be seen from the results that the fluorescence is the highest for the plate with multiple layers of tape. Thus putting extra tape on the wells changes the fluorescence of the system. As it has been seen before, evaporation of samples results in greater fluorescence, thus there is more evaporation in the multi-layered plate.
For the pipetting sample, two readings were taken for each data point. One before and one after pipetting the mixture. It can be seen that pipetting disrupts the reaction as fluorescence after pipetting increased to a very high value.
The PCR method seems to have the least fluorescnce out of all the samples. As PCR method requires pipetting and centrifuging (not tested here), there will be a lot of disruption in the reaction.
Conclusion
It can be concluded from the above results that it is not possible to carry out experiments over a time period greater than one day (about 9 hours of lab). This is as it is not possible to reduce evaporation so it is not signifcant over a few days. Having a stock solution of the reaction mixture is also not feasible as the cell extract is very expensive.
