− | As figure illustrated, His-CsgA-SpyCatcher-Histag mutant incubated with mCherry-SpyTag show a clear biofilm-associated mcherry fluorescence signal, which indicating the accurate conformation and function of the SpyTag and SpyCatcher linkage system. The distinct localization highlight of red fluorescence on E.coli, which to a large extent prove the specificity of our desired linkage between SpyTag and SpyCatcher system. | + | As figure illustrated, His-CsgA-SpyCatcher-Histag mutant incubated with mCherry-SpyTag show a clear biofilm-associated mcherry fluorescence signal, which indicating the accurate conformation and function of the SpyTag and SpyCatcher linkage system.

<h3>So far above, we proved that two engineered biofilm devices function properly. Later, we tested different inducer concentration gradient to find out the best induction condition.</h3> | <h3>So far above, we proved that two engineered biofilm devices function properly.

− | We cultured all E.coli mutants in multi-wells with increasing inducer gradient. The result demonstrated in accordance that 0.25 μg ml-1 of aTc will induce the best expression performance of biofilm, which is exactly the inducer concentration we applied in the project. | + | We cultured all <i>E. coli</i> mutants in multi-wells with increasing inducer gradient.
