Concept

We could not get enough information from normal bistable sytem experiment so that we change the system into indirect bistable system. That is because input of C or D indirectly increase the concentration of A or B so that the concentrations do not change rapidly and radically. We only input C or D, not A or B. As the diagram above, input C and D indirectly affect the cycle of bistable system. The purpose of the experiment is to attain proper data of concentrations.
Experiment
September 28th
We could not get a good result of the bistable system so that we change several part of the system. We introduce two types of DNA, "DII" and "NII", and two types of templates, "D to V" and "N to X" in the system. We change the concentration of "D to V" and "N to X", which are always the saame concentration. We also kept these tubes in 42°C.
- The Experiment of VII

- The Experiment of XII

When several hours had passed since we put these tubes in PCR, we put DII in tubes of X and NII in that of V so that the concentration of X or V might not change radically.
After putting DNAs, we kept them in PCR.
October 1st
We conducted the same experiment as what we did in September 28th. We got enough information about the experiment of VII, so we only conducted that of VII. The purpose of the experiment is to find out the best condition of the experiment of XII. We changed the concentration of CvII and X to inhV and compared the results.
- The Concentration of X to inhV: 10.00nM.
