Preparation

What Is Interlab?

This is the 5th year of InterLab and we have the following question: Can we reduce lab-to-lab variability in fluorescence measurements by normalizing to absolute cell count or colony-forming units (CFUs) instead of OD?

Materials

DNA/Plasmids

  1. Negative Control: BBa_R0040
  2. Positive Control: BBa_I20270
  3. Test Device 1: BBa_J364000
  4. Test Device 2: BBa_J364001
  5. Test Device 3: BBa_J364002
  6. Test Device 4: BBa_J364007
  7. Test Device 5: BBa_J364008
  8. Test Device 6: BBa_J364009

Apparatus

  • 96 well plates (provided by Peking University)
  • Plate reader
  • Foil covered 50 ml tube
  • Eppendorf tubes
  • Pipettes

Materials

  • LUDOX CL-X
  • Silica beads
  • Fluorescein
  • Phosphate buffered saline
  • LB media
  • Chloramphenicol
  • LB plates
  • distilled water

Protocols

We followed the protocol provided by iGEM HQ so that inter-laboratory errors can be reduced. Protocols we used can be found here:

2018 InterLab Plate Reader Protocol

Results

The results are shown in the tables and figures.
