Microtubule
Plasmid construction
We have accomplished the construction of 6 main parts whose functions are described respectively in previous design page. (Microtubule module)
Figure 1 The electrophoresis image of these 6 plasmids.
Protein expression
These are images recorded by the Fluorescence microscope.The engineered yeasts were induced at 30°C for 20 hours. And from the image, we can notice that our engineered yeasts have successfully expressed our recombinant proteins mCherry-αand mCherry. Moreover, the expression rate of mCherry is almost up to 100%.

The image shows the results of a Western blot analysis carried out with an anti-V5 antibody. The target proteins are expressed by the engineered yeasts which contain pYCα-alpha, pYCα-beta, pYCα-mCherry and pYCα-mCherry-αtubulin, respectively.

Our engineered yeasts, containing pYD1-β tubulin vector, have been proved successfully expressing exogenous βtubulin by Western blot analysis.

Flagellar Filament
Plasmid construction
We have successfully constructed the following 11 parts that have been described in detail in previous design page. (Filagellar filament module)The parts are named: , , , ,

Protein expression
The below image shows the expression of the S. cerevisiae INVSc1 cells harbouring pYCα–FliC(eGFP). The strong fluorescence signal validates the expression of recombinant protein: FilC fused with eGFP.
