Three thermocouples (Pico Technology TC-08) were attached, one to the wire in contact with the insulation using blue tack, one suspended in the liquid medium 5mm from the wire, and one in the water bath. Power was supplied to the wire at 5A, 1.8V for 600s, generating a small temperature increase of approximately 2&deg;C above room temperature (23 &plusmn; 1&deg;C) to avoid convection effects.

                 <p id="pp">These data indicate that there is no difference in fluorescence between either KillerRed or KillerOrange and the cells only control either with or without induction with IPTG. There could be several reasons for this, including the light was not intense enough to excite the fluorescent proteins, however no fluorescence from this type of the test with a laser for excitation would be unlikely.  It is also possible that no protein is being produced, which could be due to insufficient IPTG. However, the RFP in J04450 under the control of the lac-repressible promoter R0010 clearly shows that in the DH5α.Z1 strain, there is less fluorescence without IPTG, than with IPTG. This is not a perfect control for the concentration of IPTG used unless KillerRed and KillerOrange also have the R0010 promoter. Interestingly, in the DH5α strain, there is no significant difference between RFP fluorescence with or without IPTG – this is due to DH5α not having a functional copy of LacI, the lac repressor, therefore lac-repressible promoters are not “OFF”, so cannot be switched “ON” by IPTG induction. </p>

Edinburgh’s 2016 under-graduate team is utilising the natural information storage capability of DNA to store digital information. Currently they have outlined a method for using a base 4 system to store words in biological material called “BabbleBlocks”. During the Westminster UK iGEM meetup Edinburgh talked about the issue of mutated DNA going relatively undetected. Their method at the time involved adding up the value of each base and storing this as a “Checksum” at the end of the BabbleBlock. Edinburgh’s team highlighted in their presentation that they knew this would lead to a large amount of false positives as many different combinations of information could add to the same Checksum. My research looks in to the method of the Checksum and attempts to create a new method that has a smaller chance of false positives.
