Introduction

We participated in InterLitab, as we want to be contribute to the scientific progress made through this globe spanning project. In InterLab, 6 test devices are inserted in E.coli D5 α, and the growth and fluorescence is measured.

We used the following plasmids provided by iGEM HQ to transform E.coli:

  • Positive control
  • Negative control
  • Test Device 1: J23101+I13504
  • Test Device 2: J23106+I13504
  • Test Device 3: J23117+I13504
  • Test Device 4: J23101.BCD2.E0040.B0015
  • Test Device 5: J23106.BCD2.E0040.B0015
  • Test Device 6: J23117.BCD2.E0040.B0015

Calibrations

Before our measurements began, we performed some calibrations: First an OD600 reference point for our plate reader, performed with LUDOX according to the protocol. Here we found a correction factor which can be used to calculate OD from measured absorbance. Our correction fator is 3.11.

Secondly we made a fluorescence standard curve with a serial dilution of fluorescein (figure 1). We used the lower 5 data points to calculate a mean µM fluorescein pr a.u. We chose to use the lower concentration range due to two factors: 1) Linearity is better for the lower fluorescein concentrations, and 2) our measured data has a maximum fluorescence of 500, which makes it more important to have a good fit in the lower range.
