Week 15

--Monday 9/19/11--

After the calibration run that we did late last week, we think we know what the actual values for our old arabinose stock were. Unfortunately, where our data started to line up was at the very end of the serial dilution, so we think our new stocks need to be diluted more. We're going to do one more calibration run just to make sure that we really have calibrated our data. We can't afford to make assumptions that aren't true at this point! Until we confirm this, we'll keep characterizing LacI mutants with the old uncalibrated stock.

Good news at the end of the day, we've finally figured out what our old arabinose concentration really was!
