Transformation with biobricks
After designing the biobricks we proceeded to transform those we needed, using a method of chemical transformation and with competent cells prepared with a new improved protocol.

In the first transformation that we did, we had a low efficiency. We only obtained colonies of the biobricks with resistance to kanamycin. Because of it we prepared plates with lower Ampicillin's concentration (50 g/ml).

We increased the efficiency of transformation adding one more step to our protocol: 1 min in ice after the 45 s in 42ºC.

We extracted the plasmidic DNA (minipreps) with the kit Wizard Plus SV Minipreps DNA Purification System (Promega) (PROTOCOL).
