InterLab
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
- Negative Control: BBa_R0040
- Positive Control: BBa_I20270
- Test Device 1: BBa_J364000
- Test Device 2: BBa_J364001
- Test Device 3: BBa_J364002
- Test Device 4: BBa_J364007
- Test Device 5: BBa_J364008
- 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 ProtocolHelp: Protocols/Transformation
Results
The results are shown in the tables and figures.
