Interlab


     Introduction


We took part in the Fifth International InterLab Measurement Study which ains to achieve the purpose of comparative measurement. The goal of this study is to obtain large amounts of data from labs across the world,to develop absolute units for measurements GFP in a plate reader to eliminate variation between labs.





Materials


Plate reader: Synergy H1 (Biotek)
Plate reader plates: Corning 3603 96-Well Microplates (black plates with clear flat bottom)
Cell culture shaker: ZWYR-200D

Devices:
Negative control :BBa_R0040
Positive control :BBa_I20270
Device 1:BBa_J364000
Device 2:BBa_J364001
Device 3:BBa_J364002
Device 4:BBa_J364007
Device 5:BBa_J364008
Device 6:BBa_J364009

Note: for Device 5, we have not transformed it into DH5⍺ competent cells successfully for many times, therefore, we thank IGEM team of Nanjing University for providing the Device 5.
Calibration material: Provided in the 2018 IGEM distribution kit
Microorganism: Escherichia coli DH5⍺ strains





Methods


Following iGEM requirements, Team AHUT_China performed measurements according to these 2018 InterLab Protocols https://static.igem.org/mediawiki/2018/0/09/2018_InterLab_Plate_Reader_Protocol.pdf





Results


1.OD 600 reference point

Using OD 600 and H2O to generate the conversion factor for the transformation later. The average of OD600 is 0.063; the correction factor (OD600/ABS600) is 3.500





Fig. 1 LUDOX correct value




2.Particle standard curve

We obtained the two Particle Standard Curve (normal and log scale).




Fig. 2 Particle Standard Curve




Fig. 3 Particle Standard Curve (log scale)




3.Fluorescein standard curve

Dilution serious of fluorescein were prepared and measured in a 96 well plate. A standard curve is generated to correct the cell based readings to an equivalent fluorescein concentration.We obtained the two Fluorescein Standard Curve (normal and log scale).

Fig. 5 Fluorescein Standard Curve (log scale)




4.Cell measurements




Fig. 6 Fluorescence Measurements Curve




Test devices 1 and 4 show high fluorescence intensity. Test devices 2 show a modest fluorescence intensity alone with positive control group, while devices3,5,6 barely show low fluorescence intensity alone with the negative control group.

5.We obtained the Colony Forming Units per 0.1 OD600 E. coli cultures

Discussion

For Figure 3, the log graph isn’t a straight line but not 1:1 slope. In figure 6, highest fluorescence was obtained from device 4, closely followed by test device 1. Test device 2 and positive control group show a modest fluorescence intensity and device 5,6 show low fluorescence intensity, while test devices 3 barely have any fluorescence signal as well as the negative group.





Conclusion

In the case of complying laboratory safety guidelines , we completed the protocol and achieved the expected results.We completed the interlab form, which proved that we made contributions to the interlab study.
