This year, we completed the 2017 Interlab to qualify for the bronze medal! Below you can find
our data including our completion of the competent cell test kit, our reference points to
determine background fluorescence, our standard curve, and our raw data. We collaborated
alongside Cadets2Vets to determine a conclusion from each other’s data and the variation of
results from team to team.
Note: We used a Molecular Device SpectraMax M5 Plate Reader to perform the Interlab
Competent Cell Test Kit:
First, the students performed the Competent Cell Test Kit following the protocol provided by iGEM. The students used E. Coli DH5a as the competent cells being tested. The competent cells were grown on Chloramphenicol plates and left over night. In the morning, the plates showed a significant amount of growth, in the form of distinct pink colonies that the students believed would be easy to count without assistance. Luckily, Dr. Harbaugh suggested an easier method for counting: using a sharpie to dot each colony and then a clicker so we wouldn’t lose our place. After the students counted, the results were:
|Concentration of Plasmid DNA
||Number of Single Colonies
From left to right: 10 pg/μl, 50 pg/μl, and 100 pg/μl
