Instrumentation: Hardware implementation


Our device, reaching perfection!


Our device is close to being implemented. The filtered photoresistors are placed now in the right position, the motory circuit is also functioning, the main chassis of the device is constructed and painted. However, the mirrors which will be used to surround the cuvettes are still missing and so is the mechanical coupler designed by us and being constructed at the Instrument shop of the Engineering Department. The device is also powered by a 9V battery, without the need to be connected to the computer.

Ratiometrica: PCR of vectors, CFP, YFP, Promotor, Terminator and mOrange


  • Plasmid PJS 130 used as our backbone for isolating the magnesium riboswitch and constructing the fluorescent ratiometric plasmid.
  • Parts from registry amplified: E0020 (CFP), B0015 (Terminator), K143083 (Pveg) and E0030 (YFP).

Ribosense & Ratiometrica: Gel electrophoresis of PCR products


Vector amplification gel. Lanes 2-4 Lux containing vector. Lanes 5-7 Fluorescent construct vector. No products from this gel were amplified.
Various. Lanes 3-5 mOrange amplification. Lanes 6-8 eCFP (E0020) amplification. mOrange amplification did not work.
Small products for fluorescent construct. Lanes 1-3 Terminator (B0015). Lanes 4-6 Promotor pVEG + SpoVG (K143053).
Various. Lanes 2-4 eYFP (E0030) amplification. Lanes 5-7 Mg2+ vector +8 codons. Lane 8 Mg2+ vector -8 codons. Lane 8 amplification did not work.
Mg2+ riboswitch gel. Lanes 6+7 positive and negative controls respectively for entire run. Lanes 3-5 genomic riboswitch amplification -8 codons. Lanes 2+3 vector -8 codons.
  • PCR fragments for Mg2+ riboswitch, luxA/mOrange fusion and fluorescent construct from yesterday separated on gels. 90mins at 100V.
  • Mostly successful, but will need to repeat four runs: Three vectors (fluorescent, fusion (lux) and Mg2+ riboswitch (-8 codons) and mOrange gene.


Ribosense & Ratiometrica: Purification of successfully amplified DNA from gel


  • Successful CFP, YFP, B0015, Pveg + SpoVG (K143053), riboswitch and vector DNA extracted from gel and purified using a minelute column. DNA frozen for later Gibson assembly.
