Team:CSU CHINA/InterLab



Inerlab has come to the fifth session as a yardstick for measuring whether the standards of various laboratories around the world meet the requirements. Through standard curve measurement, 96-well plate readings and colony calculations, teams are able to ensure the measurement capabilities of each laboratory. Interlab not only provides a basis for comparison between different laboratories, but also provides a basis for accurate research in synthetic biology.



Positive Control (BBa_I20270): well 2B

Escherichia coli strain DH5α


10ml 1X PBS
LB (Luria Bertani) media

 Chloramphenicol (stock concentration 25 mg/mL dissolved in EtOH)


96-well plate
50 ml Falcon tube (or equivalent, preferably amber or covered in foil to block light)
1.5-ml Eppendorf tubes for sample storage, ice bucket with ice
Micropipettes and tips


There are 3 different parts of Interlab, including calibration, cell measurement and colony forming units. Calibrations are made up of OD6 00 Reference points, Particle Standard Curve, and Fluorescence standard curve, using LUDOX CL-X, Silica beads – Microsphere, Fluorescein provided in kit to generate a standardized curve. Cell measurement has 8 plasmids (Positive Control, Negative Control, Test Device 1, Test Device 2, Test Device 3, Test Device 4, Test Device 5, and Test Device 6) from Kit Plate 7 were transformed into E. coli DH5-alpha cells. After transformation and cultivation, the cells were used for experiments through the protocol. The third part is a procedure that aims to calibrate OD600 to colony forming unit (CFU) counts, which are directly relatable to the cell concentration of the culture.
