| - | <p>Our iGEM team prepared three different BioBricks: BBa_K881000 (R-GECO), BBa_K881001 (G-GECO), BBa_K881002 (B-GECO). These three GECO proteins, which are obtained from ''Zhao et al. 2011''<html><a href="#ref_zhao" name="text_zhao"><sup>[1]</sup></a></html>,

| - | The GECO’s, R-GECO (red), G-GECO (green) and B-GECO (blue) are the biobricks we will send to the registry. Those biobricks can be used in yeast and in E.coli cells. The protocol attached with the biobrick-library didn’t work for us. We used our own restriction and ligation protocols to develop the biobrick.</p>

| - | <p>The permission we needed to add the GECO’s to registry library was not easy to get. You can read more about this struggle at the Considerations-page.</p>

| + | |
| - | <p>E. Coli strain BL21 transformed with Part BBa_K881000 and Part BBa_K881001 ligated into vector pET_28a were cultured in LB media containing 100 µg/ml kanamycin for ~4 hours at 37°C. The growth rate was followed by use of OD600 measurements (see figure on the right). Then the culture was induced at an OD600 of 0,82 absorption units with 100 µg/ml IPTG.</p>

| - | <h3>Harvesting and Purification</h3>
| + | |
| - | <p>After induction for 15 hours, the cells were harvested and lysed with 5ml BugBuster containing 1µl/ml Benzonase. The supernatant of this suspension was put on a Ni-NTA column for purification and afterwards put on a PD10 column and washed with a TRIS buffer containing NaCl to remove all the calcium molecules. Then, an SDS-gel was prepared to check the purity of the GECO proteins (See figure below).
