SDS-PAGE Confirmation for Plasmids
Please refer to Improvement (For a Better Glee) in Strains comparisons.
Future Work (Keep Practicing)
Oh, no, time is up for iGEM Competition, our glee has no more time to play, but pack their luggage and head for MIT. But let's see what they have made so far and what they still have to do if they really want to be a success.

Need to do:
Microfluidic
Have done:Finished building two different arrays, find basic testing parameters.
To do:Confirm more suitable microfluidic parameters for oscillation.
Strain
Have done:Confirmed DH5a's incompetent in express oscillation;
To do:Make a comparison between BL21 (WT) and BL21 (DE3) in SDS-PAGE and so on.
Copy number
Have done:Have done: Compared the arrangements of high-middle-low copy number and middle-middle-low copy number's effect on oscillation.
To do:Try other arrangements..
Fast Degrading Tag
Have done:Found LVA-tag is not fast enough for our oscillation circuit.
To do:Try LAA or other fast degrading tag for comparison.
