See the team section for details of who participated on each committee.
Assigned team members to research the 3 most promising ideas:
We discontinued the capacitive sensor because it would take too long to develop, especially with our group’s lack of electrical experience. Attention will be shifted fully to the protein biosensor approach.
The team mainly did wetlab work this week, see the wetlab notebook for more details.

Resuspended DNA in selected wells from iGEM distribution and transformed to NEB 10-β cells.
To grow up and miniprep increased concentrations of the DNA in the distribution.
Following the iGEM kit plate instructions
Started overnight cultures, picking out satellite colonies from the plates that were transformed from iGem’s distribution kit.
Following our overnight culture procedure
Mini prepped and made glycerol stocks of the iGEM distribution kit cultures
Performed a transformation, transforming blac and fluc
Followed procedure for well plate extraction, extracting both fluc and blac. Transformed both fluc and blac, and plated in LB+carb broth, then left in the incubator overnight
Mini prepped the rest of the prepared bacteria cultures samples from 8/15
Ran gels for the miniprepped samples from 8/16
To see what was produced from the minipreps
