Experiment:
Different concentrations of IPTG were added to a 96-well plate of e-coli Top 10 cells containing LacI-RFP genetic constructs. Here we measured the optical density of the cells over-time, for different concentrations of IPTG to monitor the effects in the culture. The IPTG growth curve results are plotted below:
Figure 1: Effects of [IPTG] on cell growth: Note that the high initial OD value results due to cultures having grown for 1 hour prior the start of the measuring phase.
Simply plotting the raw data does not give sufficient information about possible trends.
Therefore, further analysis was performed where:
1. The blank absorbance level was estimated
