<p>Prepare competent cells (Escherichia coli strain DH5α) and perform transformation according to the cell measurement protocol. Meanwhile, we followed the calibration protocol supplied by the iGEM HQ to generate OD600 reference point, particle standard curve and  fluorescence standard curve to calibrate the plate reader (96 well plate) and then measured both the fluorescence and absorbance of our samples in 0-hour and 6-hour.  </p>
 
<p>We used the setted protocol that we obtained so as to ensure everyone was doing correctly and repeatable. These can be found at <a href="https://2018.igem.org/Team:SCAU-China/Protocol">this page.</a></p>
 
<h1>Results and discussion</h1>
 
<p>We submitted the iGEM’s completed spreadsheet to the measurement committee before the deadline, and received confirmation that the results were shown here: 2018/7/30</p>

<p>Our goal is to reduce lab-to-lab variations in fluorescent intensity measurements, in order to test the variation in our sample, we caculated coefficient of variation for both colony, and compared the CV value by using different normalization method (fluorescence per OD or  fluorescence per particle)</p>

<p>After 6 hr growth, we found that the variation of each type of cells (devices) is decreased, but the CV value of devices 4 and device5 are much higher than the others. The variation of fluorescence per OD is much smaller than fluorescence per particle. Furthermore, we also found that the data from colony 2’s is usually more steady compared with colony 1.
 
To conveniently compare the normalized value with original value, we removed the data of devices 4 and device 5, and only compare to the 6-hour’s data of colony 2 .

<p>According to the graph, we found that fluorescence per particle could decrease the variation but it  depending on the devices. It seemed that usage ofe OD value to normalize is still better than particle. But one thing need to be pointed out that too steady normalized value will lose sensitivity when test the influences of some factors.  You can see this <a href="https://static.igem.org/mediawiki/2017/e/ef/T--oxford--interlab-data.xlsx">excel file</a> to check our raw and manipulated data.

2. Basic parts and Composite Part

(1) BBa_K515107

We characterized the BBa_K515107 part comprising the coding sequence BBa_K515007 which coded for Dendra2, a photoconvertible reporter protein under the control of the repressible promoter TetR (BBa_R0040) and the RBS (BBa_B0034).

(2) BBa_K2559000/ BBa_K2559001/ BBa_K2559002

This three parts were obtained from the Acetobacter Xylinum bacterial cellulose synthase, as they were suspected to function together to regulate the expression and secretion of bacterial cellulose.

This bcs Z(BBa_K2559000) is coding an endoglucanase in the process of cellulose hydrolysis, bcs H (BBa_K2559001) can express cellulose complement protein A which affects the expression levels of bcsB and bcsC, interacts with bcsD. bglX (BBa_K2559003) is a β-glucosidase.

(3) BBa_K2559003/ BBa_K2559004/ BBa_K2559011

This three parts BBa_K2559000, BBa_K2559001 and BBa_K2559002 were obtained from E. coli, and but the promoters (PrplJ, PdapA, PcaiF) are totally different in expressional intensity.

(4) BBa_K2559007/ BBa_K2559008/ BBa_K2559012/ BBa_K2559013

This four parts BBa_K2559007, BBa_K2559008, BBa_K2559012 and BBa_K2559013 were used for the construction of our synergistic recombination and CRISPR/cas9 kit
