+ | <h3> Characterization </h3> | ||
+ | <p>In order to characterize the ccdB biobrick, we sent the biobricks to sequencing and made a screen of activity for the protein ccdB. We did a $\small killing$ $\small assay$, because of the toxic property of ccdB.<br> | ||
+ | |||
+ | We constructed 4 different colonies including one with the plasmid pKK-233-ccda, another with pBAD33-ccdB, a third with both, and a control colony. The ccdA gene encoded for a protein wich acts as an anti-toxin of ccdB.<br> | ||
+ | |||
+ | On the first media containing IPTG (inducing the pKK233’s expression) and glucose (repressing the pBAD expression), each colony grew. That allowed us to control the non toxicity of ccdA. | ||
+ | On the media containing both IPTG and arabinose, the strand with pBAD is killed and the strand with both ccdA and ccdB grew.<br> | ||
+ | |||
+ | We made dilution to assure that the cell concentration didn’t affect the toxicity or the anti-toxicity.</p> | ||
