Experiments of Biobricks

At this first moment, we worked on the confirmation of every biobrick that should be used in the project. We transformed and analyzed all the biobricks, using minipreping, nanodroping, digestion and electrophoresis gel. This time was reserved to train everybody in lab techniques, testing protocols and adjusting of the project.

The follow biobricks were confirmed along April and May. On Hotta's Lab participated Lilian, Otto, Daniel, Pedro and Luiza. On Clesley's Lab, only Fernando

We had issues in the confirmation of small parts (<100 kb), due to the resolution of gel. After this period, we shared the assemblies that should be done in order to start the tests of the system.
