We are starting to gather data at a very fast pace. The current schedule is to let each plate incubate for either 6 hours at 37 °C or 18 hours overnight at room temperature, and then to run each plate for 6 hours in the Tecan at 37 °C. This allows us to get in three runs a day: one at 8:00 am, one at 2:00 pm, and one at 8:00 pm. Thankfully we have a hardworking team that is dedicated to keeping the Tecan running 24/7! | We are starting to gather data at a very fast pace.

Today marked the beginning of our characterization of R0010 mutants. We plan on characterizing six mutants at a time by running many 96-well plates (8 rows, 12 columns) through the Tecan. We will have six rows for mutants, one row for wild type, and a final row for our controls. Each plate will have a constant arabinose level in all wells (except the controls) and will have 4 levels of IPTG induction across each row. Not only will we be able to get a lot of data about how each mutant responds to various repressor concentrations, but we will determine a good range of arabinose and IPTG levels to test over in the upcoming weeks.
The first characterizing run will be for our "good mutants" #1-6 at 0% arabinose. The four levels of IPTG that we have decided to start with are 0 mM, 0.25 mM, 0.5 mM, and 1 mM.

So far, we have been able to add runs with 0.1% arabinose, 0.01% arabinose, and another 0% arabinose (all at 0 mM, 0.25 mM, 0.5 mM, and 1 mM IPTG levels) to our list of completed runs.

Today we reevaluated the arabinose levels that we plan to use in our run. The original plan was to try different values on a logarithmic scale (0%, 0.001%, 0.01%, etc.), but the strain we are currently using (bw22826) shows a more linear reaction to various arabinose levels. We are instead going to try value between 0% and 1%, where we believe 0% to be minimal repression and 1% to be near maximal repression.
We have put in a 0.5% arabinose run (still with varying IPTG levels of 0 mM, 0.25 mM, 0.5 mM, and 1 mM) and are setting up a 0.75% and a screen for C0012 repressor mutants.
