MoClo Level 1 RFP reporter with AE fusion sites

pJ04B13Rm_AE

This is a MoClo Level 1 reporting device containing the Level 0 parts J23104_AB, BCD13_BC, E1010m_CD, and B0015_DE within the DVL1_AE backbone. The flanking fusion sites are A on the 5' side and E on the 3' side of the insert. The fusion site letters refer to 4bp fusion sites: A = GGAG; B = TACT; C = AATG; D = AGGT; E = GCTT; F = CGCT; G = TGCC; H = ACTA. In the given sequence the internal fusion sites are incorrectly duplicated. See Level 0 pages for further information.

This part contains a bicistronic design (BCD) element as the 5' UTR regulatory part from Mutalik et al., 2013. From the library of BCDs, this devices contains a MoClo version of BCD13 (BioFAB # apFAB691) and we obtained the sequence data for this part from the BioFAB.

Characterization

We characterized this part using flow cytometry. The cells were grown overnight into stationary phase prior to a 1:200 dilution into 1XPBS, which was then run on a SORP LSRFortessa machine. We then used the TASBE tools to analyze our data and convert our readings into molecules of equivalent fluorescin (MEFL).

By converting the flow cytometry data into MEFLs, we now have an absolute unit of measurement for comparison.

The data is binned by fluorescence intensity and the tool also provides the cell count for each bin. We can see the population has a wide distribution of expression (top graph, blue bars).

The bottom graph shows the same data as the one above, but this is now ordered by cell count, from highest (dark purple) to lowest (pale purple).

We can now see that within the population of cells, the smallest binned group shows the highest level of expression. This may be due to higher copy counts of plasmids within that subpopulation of cells.
