<p id="pp">Competent cells of E.coli DH5α were prepared following the provided protocol. Tested the OD of the cells using standard settings (see iGEM 2016 file),aiiming for a reading of 0.4-0.5. The first reading produced an average of 0.2, after 15 minutes the average increased to 2.5. The cells were spun down and re-suspended in TF-1 and TF-2 buffer. 100µl was aliquoted into 1 ml Eppendorf tubes and immediately dropped into liquid nitrogen. The cells were then left in the -80°C freezer. Chloramphenicol was made as a stock of 25mg/ml (weight measured was 76.6mg) and added to LB media to make plates for the iGEM interlab parts transformed with different constructs.</p>

<p id="pp">The InterLab measurement kit contained 5 devices; (1) J23101+I13504, (2) J23106+I13504, (3) J23117+I13504, Positive and Negative control. The first attempt to transform 5µL of each device into our competent cells found no liquid in the tubes provided. The provided tubes were re-suspended using elution buffer from a Qiagen mini-prep kit. A transformation of plasmids used in the lab under a strong promoter and GFP was performed mirroring the Interlab protocol to determine if the cells were competent. Spread plates were made and incubated at 37°C.</p>

Contruct	Starting OD
P1	0.701
P2	0.614
P3	0.615
Positive	0.587
